Psalms 80:15

15. And the vineyard which thy right hand hath planted כנה , ( kannah,) translated “vineyard,” signifies a layer-plant, or shoot. Its etymological sense, figuratively applied, takes us back to the germ life of the nation, when first planted in Canaan. Adopting the version of Gesenius we may read: “Behold and visit this vine; even the tender shoot which thy right hand hath planted.” The appeal is pathetic, like that of the infant child to the parent, and the successive pleas, “look down,” “behold,” “visit this vine,” indicate the earnestness of the prayer.

And the branch that thou madest strong for thyself The Hebrew reads, The son that thou hast strengthened; but though the figure is changed the sense is “branch,” or vine.
