I have paid careful attention.
They do not speak what is right.
No one regrets his evil,
asking, ‘What have I done?’
Everyone has stayed his course
like a horse rushing into battle.
⁷ Even storks in the sky
know their seasons.
Turtledoves, swallows, and cranes
are aware of their migration,
but my people do not know
the requirements of the Lord.

(Jeremiah 8:6-7 -- CSB)
