ka.phaph denotes bowing down, especially of a head or of persons described as bowed down; its heart-context is less clear.

The attested use chiefly concerns bowing or being bowed down: a head is bowed in Isaiah 58:5, a speaker asks about bowing before God in Micah 6:6, and bowed persons are raised in Psalm 145:14 and Psalm 146:8. Psalm 57:7 places a perfect form in a repeated declaration about the heart, where the precise contribution is less certain.

1. Bowing the head or being bowed down · dominant

   In Isaiah 58:5, the infinitive construct occurs in the question about bowing the head like a reed; the APB renders the clause “to bow the head like a reed.” In Micah 6:6, the Niphal imperfect occurs in the speaker's question about bowing before God, while Psalm 145:14 and Psalm 146:8 use passive participles for those whom the LORD raises; the APB renders them as “those who are bowed down.”

2. A repeated statement concerning the heart · rare

   In Psalm 57:7, the Qal perfect appears in the repeated clause about the speaker's heart. The APB renders the repeated statement, “My heart is prepared,” but the translation does not isolate the term's specific contribution.

   Psalm 57:7

In the Anselm Project Bible: The APB presents the dominant contexts with “bow,” “bowed down,” and “raises up,” while Psalm 57:7 is rendered “My heart is prepared.” That variation does not by itself establish separate meanings.
