Deuteronomy 8:5

Summary

The verse instructs the addressee to recognize internally ("in your heart") that Yehovah's treatment of them follows the same pattern as a father's discipline of a son. The comparison is built through a parallel clause structure introduced by "as" / "so."

Key words

• ya.da'.Ta ("you will know", H3045) — qal sequential perfect, continuing the narrative chain from the previous verses; expresses an action the addressee is to undertake as a result of what precedes.
• le.va.Ve.kha ("your heart", H3824) — construct noun + suffix, forming the phrase "with your heart," specifying the internal, reflective nature of the "knowing."
• ye.ya.Ser ("he disciplines", H3256) — piel imperfect, denoting a general or habitual action performed by "a man" ('ish, H0376I) toward his own son.
• me.ya.se.Re.ka ("is disciplining you", H3256) — piel participle in construct form with the pronominal suffix, presenting Yehovah's action as ongoing/present rather than as a single completed event.
• 'e.lo.Hei.kha ("your God", H0430G) — construct plural noun + suffix, syntactically bound to the divine name Yehovah (H3068G) to form the subject of the second clause.

What the text says

The verse is structured as a two-part comparison joined by ka.'a.Sher ("just as", H9004+H0834D) and an implied "so" carried by the parallel verb forms. The first half uses the piel imperfect ye.ya.Ser, describing what "a man" ('ish) does to "his son" (be.no, H1121A + H9023), marked with the object marker 'et (H0853). The second half mirrors this with the piel participle me.ya.se.Re.ka, whose subject is Yehovah 'elohekha. The shift from imperfect (first clause) to participle (second clause) is grammatically significant: the imperfect presents the human father's discipline as a general, repeated pattern, while the participle presents Yehovah's discipline as a continuous, present-tense action directed at "you" specifically, via the attached second-person suffix -kha (H9031).

The opening verb ya.da'.Ta is a sequential perfect, meaning it picks up the thread of preceding verses and moves the address forward: the addressee is told to "know" as the next step in a sequence, not as an isolated command. The phrase 'im-levavekha ("with your heart") modifies this knowing as an internal, reflective act rather than a mere intellectual acknowledgment.

Differences between versions

The Hebrew ye.ya.Ser is a straightforward imperfect describing what a man habitually does. The LXX renders this with an optative construction, ὡς εἴ τις παιδεύσαι ἄνθρωπος ("as if someone, a man, should discipline"), introducing a hypothetical nuance not present in the Hebrew imperfect. The Vulgate's sicut erudit filium suum homo ("just as a man instructs his son") uses a present indicative, closer to the Hebrew's general/habitual sense.

For the second clause, the Hebrew participle me.ya.se.Re.ka conveys an ongoing present action ("is disciplining you"). The Vulgate shifts this to a perfect tense, erudivit te ("has disciplined you"), presenting the action as completed rather than continuous, a divergence from the Hebrew's participial aspect.
