John Trapp on Psalms 119:54

Verſ. 54. Thy ſtatutes have been my ſongs] Thy Promiſes which bind thee by Grace, as ſtatutes do us by Duty, and are every whit as ſure.Metaphora a falcibus. By theſe I lopped off my cares, fears, and griefs, as with a pruning or paring knife: ſpared them round till none was left.

In the houſe of my pilgrimage] In hoc exilio, in hoc ergaſtulo, in hac peregrinatione,Bern. in hac valle lachrymarum. Travellours ſing to deceive the tediouſneſs of the way; ſo did David. and hereby he ſolaced himſelf under that horrour, verſ. 53. great is the comfort that cometh in by ſinging of Pſalms with grace in our hearts.
