אָמַן --- He'emin (הֶאֱמִין)

MEANINGTo believe, trust, actively commit oneself in trust to. The Hiphil of aman --- active, causative, volitional. Abraham's faith in Genesis 15:6. The OT's foundational word for saving faith as genuine human act.

GRAMMARHiphil stem of אָמַן (aman --- to be firm, reliable). The Hiphil is consistently active and causative in Hebrew grammar: the subject does something. He'emin means 'to count as trustworthy, to actively commit oneself in trust.' Not a passively received disposition but something Abraham did --- a genuine volitional act of trusting.

SIGNIFICANCEPaul's four quotations of Genesis 15:6 (Romans 4:3, 9, 22; Galatians 3:6) make he'emin the OT foundation for NT justification by faith. The Hiphil form is Thread 4's most important grammatical evidence: faith is something Abraham actively did. Even if grace enables the capacity to believe, the believing itself is genuinely the person's own act.

KEY VERSE / SCRIPTURESGenesis 15:6 (the foundational occurrence, quoted four times by Paul); Numbers 14:11; Isaiah 53:1; Habakkuk 2:4 (via emunah).
