'Bow' in the Bible

“God will not turn back His anger;The [proud] helpers of Rahab [the arrogant monster of the sea] bow under Him.

“He may flee from the iron weapon,But the bow of bronze will pierce him through.

‘My glory and honor are fresh in me [being constantly renewed],And my bow gains [ever] new strength in my hand.’

Let my wife grind [meal, like a bond slave] for another [man],And let others kneel down over her.

“They kneel down, they bring forth their young,They cast out their labor pains.
