'Assemblage' in the Bible

Behold, I bring them from the north country, and gather them from the uttermost parts of the earth; and among them the blind and the lame, the woman with child and her that travaileth with child together: a great assemblage shall they return hither.

Then all the men who knew that their wives burned incense to other gods, and all the women who stood by, a great assemblage, even all the people that dwelt in the land of Egypt, in Pathros, answered Jeremiah, saying,

For behold, I will raise and cause to come up against Babylon, an assemblage of great nations from the north country; and they shall set themselves in array against her: from thence shall she be taken. Their arrows shall be as those of a mighty expert man: none shall return empty.
