Psalms 72:15-16

In return for his beneficent rule, the king would receive the blessing of his people. They would express their gratitude by bringing him wealth (cf. 1 Kings 10:10) and by praying for him. As a result of his good influence, his lands would enjoy prosperity, which Solomon compared to abundant crops, favored trees, and flourishing citizens.

"This verse [16], and the Psalm as a whole, shows that what we call the ’moral realm’ and the ’realm of nature’ form one indivisible whole to the Israelites. A community which lives according to righteousness enjoys not only internal harmony, but also prosperity in field and flock." [Note: A. A. Anderson, The Book of Psalms, p. 525.]
