John Trapp on Psalms 64:7

Verſ. 7. But God ſhall ſhoot at them, &c.] He ſhall overſhoot them in their own bow, pay them home in their own coyn; he will deal with them lege talionis, for he loveth to retaliate, ſee verſe 4. they ſhall find that he can handle his armes a fair deal better againſt them, than they did againſt David.

With an arrow ſuddenly] As was Ahab, and the rich fool, Luk. 12. whiles he ſat pruning himſelf like a bird on a bough, death fetch'd him off ſuddenly by his ſhaft ſhot at him, and down he came tumbling. See 1 Theſ. 5.3.
