John Gill Commentary Jeremiah 27:2

"Thus saith Jehovah to me: Make thee bonds and bars, and put them upon thy neck;" — Jeremiah 27:2 (ASV)

Thus says the Lord to me, make you bonds and yokes The yokes were made of wood, as appears from (Jeremiah 28:13); and the bonds were strings or thongs, which bound the yoke together, that it might not slip off the neck, on which it was put.

and put them upon your neck; not all of them together, but one after another, at different times; and this was very significant;

for the prophet being seen abroad with a yoke upon his neck, it would be natural to inquire the meaning of it; when they would be told it was to signify the subjection of Judah, and so of other nations, to the king of Babylon; and that he did wear at times such a yoke, even fifteen years after, in the fourth of Zedekiah's reign, appears from (Jeremiah 28:1Jeremiah 28:10).
