Topical Lexicon Orthographic Variation and Identity Strong’s 3446 represents the alternate spelling יִשְׂחָק for the patriarch Isaac. While the usual spelling (Strong’s 3327) employs a tsade, this rare orthography uses a sin yet points to the same historical person. The variant does not suggest a different individual but highlights the flexibility of Hebrew orthography in later poetic and prophetic texts. Occurrences in Scripture 1. Psalm 105:9 These four appearances cluster in passages that rehearse covenant faithfulness or deliver prophetic warning, showing Isaac’s name functioning as a covenant marker and as a corporate title for Israel. Covenant Continuity Isaac is the indispensable middle link in the “Abraham, Isaac, and Jacob” triad. Psalm 105:9 recalls “the covenant He made with Abraham, and the oath He swore to Isaac.” By naming Isaac, the psalmist stresses that the promises were not a one–generation event but a trans-generational oath. Jeremiah 33:26 repeats the triad to guarantee that God’s commitment to Davidic rule and national restoration is as certain as His covenant oath to the patriarchs. Isaac in the Worship of Israel Psalm 105 appears in a liturgical setting that invites corporate remembrance. Isaac’s inclusion affirms that God’s people worship the One who binds Himself to generations, strengthening faith in seasons when fulfillment seems delayed. The psalmist’s choice of the rarer spelling may underscore poetic parallelism with surrounding lines. Isaac in the Prophets Amos employs “Isaac” as a synonym for the Northern Kingdom. “The high places of Isaac will be destroyed” (Amos 7:9) turns the patriarch’s honored name into an indictment of covenant breach. In Amos 7:16, the opposition to Amos is framed as protecting “the house of Isaac,” exposing the irony that those claiming patriarchal heritage resist the prophetic call to repentance. The shift from covenant promise (Psalm 105; Jeremiah 33) to covenant lawsuit (Amos 7) demonstrates that Isaac’s legacy includes both blessing and accountability. Theological Portrait 1.
