1 Samuel 18:21

And Saul said, I will give him her, that she may be a snare to him, and that the hand of the Philistines may be against him. Wherefore Saul said to David, Thou shalt this day be my son in law in [the one of] the twain.

Ver. 21. Thou shalt this day be my son-in-law.] Here is a fair glove drawn upon a foul hand; there is a great deal of such colluding and colloguing in the world. "Be wise as serpents."

“ Sit licet in partes circumspectissimus omnes,

Nemo tamen vulpes, nemo cavere potest. ”
