Then came the word of the Lord unto the Prophet Jeremiah,.... At the time when the messengers came to him from the king to pray for them; for Jeremiah 37:4 are to be included in a parenthesis:
saying; as follows: which is an answer to the messengers.

Then came the word of the Lord to this effect: Jeremiah 37:7. "Thus saith Jahveh, the God of Israel: Thus shall ye say to the king of Judah who hath sent you to me to ask at me, Behold, the army of Pharaoh, which marched out to your help, will return to Egypt, their own land. Jeremiah 37:8. And the Chaldeans shall return and fight against this city, and take it, and burn it with fire. Jeremiah 37:9. Thus saith Jahveh: Do not deceive yourselves by thinking, The Chaldeans will quite withdraw from us; for they will not withdraw. Jeremiah 37:10. For, even though he had beaten the whole army of the Chaldeans who are fighting with you, and there remained of them only some who had been pierced through and through, yet they would rise up, every man in his tent, and burn this city with fire." In order to cut off every hope, the prophet announces that the Egyptians will bring no help, but withdraw to their own land before the Chaldeans who went out to meet them, without having accomplished their object; but then the Chaldeans will return, continue the siege, take the city and burn it. To assure them of this, he adds: "Ye must not deceive yourselves with the vain hope that the Chaldeans may possibly be defeated and driven back by the Egyptians. The destruction of Jerusalem is so certain that, even supposing you were actually to defeat and repulse the Chaldeans, and only some few grievously wounded ones remained in the tents, these would rise up and burn the city." In הלוך ילכוּ the inf. abs. is to be observed, as strengthening the idea contained in the verb: "to depart wholly or completely;" הלך is here to "depart, withdraw." אנשׁים in contrast with חיל are separate individuals. מדקּר, pierced through by sword or lance, i.e., grievously, mortally wounded.
