Jeremiah 18:17

I will scatter them as with an east wind before the enemy,
&c.] As the east wind, which is generally strong and boisterous, drives the chaff and stubble, and anything that is light, before it, and scatters it here and there; so the Lord threatens to scatter the people of the Jews over the face of the earth, before their enemies, whom they should not be able to withstand. It denotes the power of the enemy God would make use of; the ease with which this should be done; and the utter dispersion of them; and is their present case: I will show them the back, and not the face, in the day of their
calamity;
that is, will not look upon them in a favourable way, nor with any pity and compassion for them, nor hear their cries; but turn his back upon them, and a deaf ear unto them, and give them no help and relief, or deliver them out of their calamities; but suffer them to continue upon them, and them to sink under them; see ( Proverbs 1:26-28 ) ; which refers to the same time of calamity as here.
