Charles Spurgeon Commentary Jeremiah 5:19

"And it shall come to pass, when ye shall say, Wherefore hath Jehovah our God done all these things unto us? then shalt thou say unto them, Like as ye have forsaken me, and served foreign gods in your land, so shall ye serve strangers in a land that is not yours." — Jeremiah 5:19 (ASV)

A man may often see his sin in its punishment. Because they had served strange gods, therefore the Lord sent them to serve strangers in a strange land.

Remember, O transgressor, that your sin will come home to you in some form or other! If we sow the wind, we shall reap the whirlwind. Whatsoever a man soweth, that shall he also reap.

Therefore, let us beware of scattering seeds of sin, for they will produce a terrible harvest of woe.
