John Trapp on Psalms 147:2

Verſ. 2 The Lord doth build up Jeruſalem] Hee is the only Architect of his Church. Hee layeth the foundation of it in election (ſaith a good Expoſitour) and buildeth it progreſſively by faith and ſanctification; and finiſheth his work of grace, and his peoples happineſs, in glorification.

Hee gathereth together the out-caſts of Iſrael] Hee will ſurely bring home his baniſhed; yea, becauſe they called thee an out-caſt, ſaying, This is Zion, whom no man ſeeketh after, therefore I will reſtore health unto thee, &c. Jer. 30.17. Qui nil ſperare poteſt, deſperet nihil.
