Have given children suck— The plural (children) is put for the singular; and possibly Sarah might flatter herself that she should have more children after this. Hence we learn, as well as from many other instances in antiquity, that women of the highest distinction did not disdain the duty of suckling their children. Modern luxury has introduced a different practice; but she who is able and omits to suckle her own child, is, without all question, deficient in one of the first and most essential duties of a mother.
