John Trapp on Psalms 119:122

Verſ. 122 Bee ſurety for thy ſervant for good] Obi vadimonium; appear for mee, and non-ſuit all accuſations againſt mee: Or, undertake for mee that I ſhall keep thy lawes, as I have ſaid and ſworne to do: Sis fide juſſor meus. Some obſerve that this is the only verſe throughout the whole Pſalm wherein the word is not mentioned under the name of Law, Judgements, Statutes, or the like tearms. And they make this Note upon it; where the Law faileth, there Chriſt is a ſurety of a better Teſtament. There are that render the words thus. Dulcify or delight thy ſervant in good, Oblects ſervum tu[illegible: 1 letter]m. [illegible: 1 letter]uſcul. that is, make him joyfull and comfortable in the purſuit and practice of that which is good.
