John Trapp on Proverbs 5:18

Verſ. 18. Let thy fountain bee bleſſed] Or thy fountain ſhall bee bleſſed, thy wife ſhall bee fruitful, as Pſal. 128. that Pſalm for Solomon, whoſe many wives brought him but few children. Wee read but of one Son that hee had (who was none of the wiſeſt neither) and two daughters, both of them ſubjects. Our Henry the 8th. (though blame-worthy for women too) was more happy in King Edward his Son (that Orbis deliciae) and his two Daughters, both Soveraigns of an Imperial Crown.

Rejoyce with the wife of thy youth] As Iſaac did, who was the moſt loving husband that wee read of in holy-writ. Ezechiels wife was the delight of his eyes, hee took ſingular complacency in her company. This conjugal joy is the fruit of love, which therefore hee commendeth to all married men, in the next words.
