That ye may suck. Restored Jerusalem will be as a mother to all who love her, to all who have mourned for her when she lay as it were dead (1 Samuel 15:35; 2 Samuel 14:2). She will have "milk" to give to all—"the sincere milk of the Word" (1 Peter 2:2)—and from her both Jew and Gentile will "suck out no small advantage" (Psalms 73:10).
She will also impart to them from the abundance of her glory.
