John Trapp on Psalms 56:2

Verſ. 2. Mine enemies (or obſervers) would daily ſwallow me up] Anhelant obſervatores mei. To ſet forth the indignity of the thing, he repeateth the ſame ſentence again in the plural number; noting, that there were not a few of them bitterly bent by might and main to miſchief him, a poor forlorn friendleſs man.

For there be many that fight againſt me, O thou moſt High] Or, though there be many that fight for me from on high, that is the Angels, as Aben-Ezra rendreth and ſenſeth the Text.
