Kaph
“Yahweh gave
Full vent
To his wrath.
He poured out
His hot anger.
He kindled
A fire
In Zion,
That consumed
Its foundations.”
Yahweh was angry at Jerusalem. Thus he vented his anger when he started a fire in Zion that consumed it down to its foundations. Yahweh, not the Babylonians, set the city on fire. This verse starts with the Hebrew consonant letter Kaph in this acrostic poem.
