John Trapp on Psalms 128:1

PSAL. CXXVIII.

VErſ. 1 Bleſſed is every one that feareth the Lord] This Pſalm is fitly ſubjoyned to the former, and it is, [non-Latin text not transcribed], a kind of wedding-ſermon, written for the inſtruction and comfort of married couples, and ſhewing that Conjugium humanae eſt divina Academia vitae. And it is to bee obſerved, that here all men are ſpoken to as wedded; becauſe this is the ordinary eſtate of moſt people. See 1 Cor. 7.1, 2. At this day, every Jew is bound to marry about eighteen years of age or before twenty; elſe hee is accounted as one that liveth in ſin; and how the Popiſh clergy, profeſſing continency, have turned all places into ſo many Sodoms, who knoweth not?

And walketh in his wayes] The true reverentiall fear of God will eaſily form the heart to a right obedience. They that fear the Lord will keep his Covenant, Pſal. 103.13. with 18. and therefore was the Law delivered at firſt in that terrible manner.
