John Trapp on Psalms 35:6

Verſ. 6. Let their way be dark and ſlippery] Heb. Darkneſſe and ſlipperineſſe. If a man have neither light, nor firm footing, and a feirce enemy at his heeles,See Jer. 23.1[illegible: 1 letter] what ſhift can he make for himſelf? The word rendred ſlippery is of a double form (like that libbi ſecharchar, my heart panteth or beateth about, throbbeth, Pſal. 38.10.) to increaſe the ſignification. The ſoul of a wicked man is as in a ſling, 1 Sam. 25.29. violently toſſed about.
