Matthew Poole and continuators on 1 Chronicles 12:22

22 For at that time day by day, there came to David to help him, until it was a great host, like the host of God .

i. e. While he was at Ziklag, and in his March to Hebron, and principally at Hebron, as the next Verse explains it.

i. e. Innumerable like the Stars or Angels, both which are called Gods hosts. Oth. the host of God, i. e. a very great Host, great things being so called, as Cedars, Mountains, &c. of God. But the particle of likeness here added excludes this Sence, for it had been very improper to say, a great host like a great host, i. e. like it self.
