Matthew Poole and continuators on Psalms 80:15

15 And the vineyard which thy right hand hath planted , and the branch that thou madest strong for thy self .

Or, the root, or stock or plant, as others render it.

Which thou hast planted or fixed with thy might and power; whereof the right hand is both a sign or symbol and an instrument.

Heb. the son (i. e.) either 1: The son of man, as it is more fully expressed, Vers. 17. Or rather, 2. The branch; for as yet he continues the metaphor; which is called the son, to wit, of the root or stock mentioned in the former clause, as the Branches are called Daughters in the Hebrew Text, Gen. 49. 22▪

Either 1. By supporting it with stakes or walls upon which the vine groweth up: Or rather, 2. By causing it to grow in bulk and thickness, and consequently in strength.

For thy own especial delight and service and honour.
