Jeremiah 42:19  (King James Version)
The LORD hath said concerning you, O ye remnant of Judah; Go ye not into Egypt: know certainly that I have admonished you this day.

God knew, that such was their miserable propensity to idolatry, that they would adopt the idolatrous worship of Egypt. Add to which, their going thither for protection was in effect refusing to submit to the king of Babylon, to whom God had decreed the rule of Judah and the neighbouring kingdoms.
