John Trapp on Psalms 127:1

PSAL. CXXVII.

A Song of degrees for Solomon] As Pſal. 72.1. Penned by David not long before his death; and left his Son Solomon, to teach him, that nothing can be gotten (or kept, no not Children be gotten) but by Gods bleſſing. This laſt was a fit leſſon for Solomon, who by ſo many wives and Concubines, left but one only ſon that wee read of, and him none of the wiſeſt. Some render it. A Song of degrees of Solomon,Lib. 3. [non-Latin text not transcribed] Cap. 1. making him the penman of it; yea Origen from this inſcription, entitleth Solomon to all the Songs of degrees; but that's not likely.

Verſ. 1 Except the Lord build the houſe] Not the Fabrick only, but the family and the Government thereof; there is no good to bee done, if God ſet not to his F[illegible: 1 letter]at, [non-Latin text not transcribed] Naz. and ſay, Let it bee done; if hee blaſt, or not bleſs mens indeavours and policies, they are all but arena ſine calce, ſand without lime, they will not hang together, but like untempered Morter, fall aſunder. There is a curſe upon ſuch as Idolize themſelves, and kiſs their own hands, though they bee induſtrious, Johoaki[illegible: 1 letter] for inſtances, Jer. 22.

Except the Lord keep the City, the watchman] Whether civill, or military: fruſtra nititur, qui Deo non innititur. Politicians ſtand on their own heads (like Children) and ſhake their heeles againſt Heaven, but all in vain. Souldiers, ſome of them are ready to ſay with Ajax, I acknowledge no God but my ſword, &c. Such ſhall bee ſurely befooled and confuted; and Gods bleſſing declared to bee all in all.
