The vineyard; or, the root, or stock, or plant, as others render it. Thy right hand hath planted; which thou hast planted or fixed with thy might and power; whereof the right hand is both a sign or symbol and an instrument. The branch, Heb. the son, i.e. either,
1. The son of man, as it is more fully expressed, Psa_80:17. 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.
Thou madest strong; 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 thyself; for thy own especial delight, and service, and honor.
