Jeremiah 13:11 - Matthew Poole's English Annotations on the Holy Bible

Here God openeth to the prophet why he commanded him to put the girdle about his loins, viz. to show that he of his singular favour had used the Jews as a man useth girdle, which he fasteneth about his loins; and as a man weareth his girdle, made up of some costly materials, for an honour and praise to him, so God's design in honouring this people, wearing them as a girdle, was, that they might bring him honour and glory, living to his praise, in the obedience of his commands, especially such commands as resisted to his worship. But they would not hear; but they would not answer God's designs, nor hearken to any counsels of that nature which he gave them, and therefore he resolved to pluck them from his loins, and to suffer them to rot and consume as that girdle was rotted: see Psalms 81:8-16, which the author of the English Annotations saith well is an excellent comment on this text.
