Question: All those who move to Egypt will die by the sword, famine, or pestilence (Jer.42:15-18). None "shall escape from the evil" that comes directly from God. But many folks, including Jews, have moved to Egypt and most seem to have escaped from God's promised evil.
Response: As is evident in Jeremiah 42:11, the prophecy found in Jeremiah 42:15-18 is specifically directed to the Jews who would seek refuge in Egypt during the time of Babylonian rule. In other words, this prophecy was to be the fate of the Jews who took refuge in Egypt during the time of Babylonian rule.
Next: Was Jeremiah wrong about Hazor? And where are the "dragons" he spoke of?
