Charles Ellicott Commentary Jeremiah 30:8

"And it shall come to pass in that day, saith Jehovah of hosts, that I will break his yoke from off thy neck, and will burst thy bonds; and strangers shall no more make him their bondman;" — Jeremiah 30:8 (ASV)

For it shall come to pass in that day ... —Better, And it shall come. Herein lies the basis of the hope expressed in the words he shall be saved out of it, which keeps the prophet from sinking under the burden of his sorrow.

The second and third person are strangely mingled. Jehovah speaks to Israel, your bonds, your yoke, and his yoke is that of the oppressor, that is, of the Babylonian ruler; and then, the person changing, strangers shall no more get service done for them by him, that is, by Israel. The prophet echoes the words of Isaiah 10:27.
