Qal Imperative, Cohortative, and Jussiveשְׁמֹר · אֶשְׁמְרָה · יִשְׁמֹר — guard! let me guard! let him guard!
Hebrew has three "volitional" verb forms — verbs that express not what is but what the speaker wills: a wish, a command, an exhortation. The imperative is the 2nd-person direct command ("guard!"). The cohortative is the 1st-person self-exhortation ("let me guard," "let us guard"). The jussive is the 3rd-person wish ("let him guard," "may she live"). Together they cover every grammatical person. This lesson teaches all three forms, the rules for negative prohibitions, and the two biblical sentences every Hebrew student knows by heart — יְהִי אוֹר and שְׁמַע יִשְׂרָאֵל.
Reveal answer
- Recognize and produce all four Qal imperative forms (2ms, 2fs, 2mp, 2fp)
- Derive any Qal imperative from its corresponding imperfect form
- Recognize the Qal cohortative (1cs, 1cp) by its final ה
- Recognize the Qal jussive (3ms, 3fs) and know when it differs in form from the imperfect
- Distinguish negative prohibitions with לֹא + imperfect (solemn) from אַל + jussive (immediate)
- Parse and translate יְהִי אוֹר "let there be light" and שְׁמַע יִשְׂרָאֵל "Hear, O Israel"
- Understand how the wayyiqtol of Lesson 18 relates to the jussive (both are shortened imperfects)
Why Volitional Forms Matter
So far in this unit you have met the Qal perfect (completed action), the Qal imperfect (incomplete or future action), the participle (ongoing characterization), and the wayyiqtol (narrative sequence). These are indicative forms — they describe what is, was, or will be.
But a huge portion of biblical Hebrew is not indicative at all. The Bible is full of commands, blessings, curses, prayers, and exhortations. When God says "let there be light," when Moses says "hear, O Israel," when David prays "let my prayer come before you" — these are not statements about reality. They are acts of will: the speaker is trying to bring something about. Hebrew has a dedicated set of forms for this kind of speech, and you cannot read most prayer, prophecy, or law without them.
Hebrew calls these the volitional forms (from Latin velle, "to will"). There are three, one for each grammatical person:
- Imperative — 2nd person: a direct command to "you" ("guard!").
- Cohortative — 1st person: self-exhortation ("let me guard," "let us guard").
- Jussive — 3rd person: a wish or command directed at "him/her/it" ("let him guard," "may she live").
The good news: all three are close cousins of the imperfect you already know. Once you can recognize an imperfect, learning the volitional forms is mostly a matter of noticing small modifications — a prefix dropped, a final ה added, a final vowel trimmed.
The Imperative — 2nd Person Direct Command
The imperative is the simplest volitional form to learn. It exists only in the 2nd person (you can only directly command someone you are talking to), and it is derived from the imperfect by stripping off the prefix.
| Person | Form | Pronunciation | Translation |
|---|---|---|---|
| 2ms | שְׁמֹר | shemor | guard! (to one male) |
| 2fs | שִׁמְרִי | shimri | guard! (to one female) |
| 2mp | שִׁמְרוּ | shimru | guard! (to several males or mixed group) |
| 2fp | שְׁמֹרְנָה | shemornah | guard! (to several females) |
How Imperatives Are Derived
The relationship between imperfect and imperative is mechanical. Once you see the pattern, you can predict the imperative of any verb you know in the imperfect.
| Person | Imperfect | Drop prefix → | Imperative |
|---|---|---|---|
| 2ms | תִּשְׁמֹר | tishmor → shemor | שְׁמֹר |
| 2fs | תִּשְׁמְרִי | tishmeri → shimri | שִׁמְרִי |
| 2mp | תִּשְׁמְרוּ | tishmeru → shimru | שִׁמְרוּ |
| 2fp | תִּשְׁמֹרְנָה | tishmornah → shemornah | שְׁמֹרְנָה |
Imperatives in Practice
Three of the most common imperatives in the Hebrew Bible.
The Cohortative — 1st Person Volitional
The cohortative is the 1st-person form. It is built by taking the 1st-person imperfect and adding a final ה (he). The meaning is "let me…" or "let us…" — a self-exhortation, a resolution, or a polite request that something be allowed.
| Person | Form | Pronunciation | Translation |
|---|---|---|---|
| 1cs | אֶשְׁמְרָה | eshmerah | let me guard, may I guard |
| 1cp | נִשְׁמְרָה | nishmerah | let us guard, may we guard |
The marker is unmistakable: a final ה written without mappiq, and the vowel under the previous consonant is a qamatz. Compare the regular 1cs imperfect אֶשְׁמֹר ("I shall guard") with the cohortative אֶשְׁמְרָה ("let me guard"). The added ה changes a statement of future fact into an act of will.
The Jussive — 3rd Person Volitional
The jussive is the 3rd-person form. It is the form God uses when speaking commands about things ("let there be light"), the form humans use when blessing or cursing third parties ("may he live!"), and the form prophets use when announcing God's decrees.
| Person | Form | Pronunciation | Translation |
|---|---|---|---|
| 3ms | יִשְׁמֹר | yishmor | let him guard, may he guard |
| 3fs | תִּשְׁמֹר | tishmor | let her guard, may she guard |
You will immediately notice: in the strong verb, the jussive looks identical to the 3rd-person imperfect. The same form יִשְׁמֹר can mean "he will guard" (imperfect) or "let him guard" (jussive). Context — particularly the presence of אַל ("do not") or a jussive sense in the surrounding clause — tells you which.
In weak verbs (especially III-he verbs like הָיָה "to be" and עָשָׂה "to do"), the jussive shows a distinct shortened form. The regular 3ms imperfect of הָיָה is יִהְיֶה "he will be"; the jussive is the shortened יְהִי "let him/it be." This is called apocopation — the trimming of a final vowel-letter.
Jussive and Imperfect — Same or Different?
The relationship between imperfect and jussive is unique to Hebrew and confuses every beginner. Here is the short version:
- Strong verbs: jussive = imperfect in form. Context determines meaning.
- Weak verbs (especially III-he): jussive is a distinct, shortened form. The regular imperfect ends in a vowel-letter; the jussive trims it off.
- Hiphil and other derived stems: jussive often shows a shortened vowel pattern even in strong verbs.
So when you encounter a 3rd-person imperfect-looking form, ask: (1) Is there an אַל negating it? Then jussive. (2) Does the context call for a wish, command, or blessing? Then jussive. (3) Is the form noticeably shorter than the regular imperfect? Then jussive. Otherwise: read it as a regular imperfect.
Negative Prohibitions — לֹא and אַל
Hebrew has no negative imperative. To forbid something, you negate a volitional or imperfect form. The choice between two negatives — לֹא ("not") and אַל ("do not") — carries an important difference in nuance.
| Negation | Construction | Force | Biblical example |
|---|---|---|---|
| לֹא + imperfect | solemn, permanent prohibition | "you shall not…" | לֹא תִגְנֹב |
| אַל + jussive | immediate, situational request | "do not…" | אַל־תִּירָא |
Walkthrough — יְהִי אוֹר
The first creative word of the Hebrew Bible (Gen 1:3). Two words, three syllables, and an entire grammar lesson packed inside.
- יְהִי — 3ms Qal jussive of הָיָה ("to be"). The regular imperfect would be יִהְיֶה ("he/it will be"); the jussive is the apocopated יְהִי ("let it be"). The final ה of the root is trimmed; only the initial yod-he survives.
- אוֹר — masculine singular noun, "light." The subject of the verb.
Word-for-word: "let-it-be light." English: "let there be light." This is the first speech act of the creating God, and grammatically it is a third-person jussive — a divine wish expressed as a command directed at a thing not yet existing.
Walkthrough — שְׁמַע יִשְׂרָאֵל
The opening of the Shema (Deut 6:4) — the central confession of Israel and the verse Jesus identifies as the foremost commandment (Mark 12:29).
- שְׁמַע — 2ms Qal imperative of שָׁמַע ("to hear, listen, obey"). The vowel pattern shows the imperative-of-a-guttural (final ayin takes patach rather than holem). Direct address: "Hear!"
- יִשְׂרָאֵל — proper noun, the vocative addressee.
The full verse reads: שְׁמַע יִשְׂרָאֵל יְהוָה אֱלֹהֵינוּ יְהוָה אֶחָד — "Hear, O Israel: the LORD is our God, the LORD is one." Recited twice daily in observant Jewish prayer. The whole confession begins with a 2ms Qal imperative.
