Jeremias 34:4 Meaning and Commentary

Jeremiah 34:4

Yet hear the word of the Lord, O Zedekiah king of Judah
Which, though a king, he ought to hearken to; and, besides, what follows was for comfort, being a mitigation of his sentence, and containing in it mercy, as well as judgment: thus saith the Lord of thee, thou shalt not die by the sword:
of the king of Babylon; or a violent death; and therefore fear not to deliver up thyself and city into his hands; which he might be twelfth to do, fearing he would put him to death immediately.

Jeremias 34:4 In-Context

3 and thou shalt send them to the king of Idumea, and to the king of Moab, and to the king of the children of Ammon, and to the king of Tyre, and to the king of Sidon, by the hands of their messengers that come to meet them at Jerusalem to Sedekias king of Juda.
4 And thou shalt commission them to say to their lords, Thus said the Lord God of Israel; Thus shall ye say to your lords;
5 I have made the earth by my great power, and with my high arm, and I will give it to whomsoever it shall seem in mine eyes.
6 I gave the earth to Nabuchodonosor king of Babylon to serve him, and the wild beasts of the field to labour for him.
