John Trapp on Psalms 41:10

Verſ. 10. But thou, O Lord, be merciful unte me] As ſtorms beat a Ship into the harbour: ſo did mens miſuſages drive David to God; and as Children meeting with hard meaſure abroad, hye home to their Parents; ſo here.

And raiſe mee up] From off this bed of weakneſſe; and from under their feet of inſolency and cruelty.

That I may requite them] Not in a way of private revenge (for that was utterly unlawfull, and would not bear a prayer) but of Juſtice, as I am a King, and a lawfull Magiſtrate. The fear of this might happily make Ahitophel (foreſeeing that all would be naught on Abſoloms ſide) to ſave the hangman a labour.
