Her children arise up,.... As olive plants around her table; grow up to maturity of age, and ripeness of judgment, and so capable of observing things, and doing the work here ascribed to them: or they rise up in reverence of her, and respect to her, suitable to the relation they stand in to her: or rather it signifies their readiness to show a regard unto her, and their setting about the work of commendation of her in earnest: or else their earliness in doing it; they rise in the morning, as Aben Ezra's note is; her lamp not being extinct in the night.
Jarchi interprets these "children" of disciples; but they are to be understood of regenerate persons, young converts, born in Zion, and brought up by her; the children of that Jerusalem that is the mother of us all, Isa 54:1;and call her blessed; bless God for her, for such a mother, and wish themselves as happy as she is; they pray for her blessedness, peace, and prosperity, as all Zion's children should, Ps 122:6; they pronounce her blessed, as well they may, since she is blessed with all spiritual blessings in Christ; and so are all in her family that truly belong to her, her children and her servants, Ps 84:4; see So 6:9;her husband [also], and he praiseth her; that is, he is ready also to rise up and speak in her praise and commendation.
Jarchi says this is the holy blessed God.
