Albert Barnes Commentary Jeremiah 2:24

"a wild ass used to the wilderness, that snuffeth up the wind in her desire; in her occasion who can turn her away? all they that seek her will not weary themselves; in her month they shall find her." — Jeremiah 2:24 (ASV)

A wild donkey used to the wilderness - The type of an untamed and reckless nature.

Snuffeth up the wind - The wind brings with it the scent of the male. Israel does not wait until temptation comes of itself, but looks out for any and every incentive to idolatry.

Occasion ... month - That is, the pairing season.
