Charles Spurgeon Commentary Jeremiah 31:8

"Behold, I will bring them from the north country, and gather them from the uttermost parts of the earth, [and] with them the blind and the lame, the woman with child and her that travaileth with child together: a great company shall they return hither." — Jeremiah 31:8 (ASV)

From the north country, and gather them from the coasts of the earth, and with them the blind and the lame,

How can they come? Will they help one another? God himself will be eyes to the blind and feet to the lame.

The woman with child and her that travaileth with child together: a great company shall return thither.

They were not fit for traveling, yet God in his great mercy can make the weakest of his people strong, and when he means to bring them to himself, they will come even though it looks as if they could not come.
