Charles Ellicott Commentary Genesis 32:2

"And Jacob said when he saw them, This is God`s host: and he called the name of that place Mahanaim." — Genesis 32:2 (ASV)

Mahanaim.—That is, the two camps, his own and that of the angels; or, possibly, two camps of angels, one on either side of him. Mahanaim was in the tribe of Gad, and became an important town. (See 2 Samuel 2:8; 2 Samuel 17:24; 1 Kings 4:14.)
