a Bible passage
a time to throw away stones, and a time to gather stones together;
a time to embrace, and a time to refrain from embracing;
5. cast away stones—as out of a garden or vineyard (Isa 5:2).
gather—for building; figuratively, the Gentiles, once castaway stones, were in due time made parts of the spiritual building (Eph 2:19, 20), and children of Abraham (Mt 3:9); so the restored Jews hereafter (Ps 102:13, 14; Zec 9:16).
