Hebrews 11:18

18. In Isaac On this phrase Alford notes: “‘Three ways,’ says Delitzsch, ‘of interpreting this are possible 1. After Isaac shall thy seed be named; 2. In, through, of, Isaac shall seed be called into being to thee; 3. In Isaac shall seed be named to thee; that is, in or through him shall it come that a seed of Abraham shall be possible.’ Then he puts aside the first, seeing that only once is the seed of Abraham called Isaac, [Amos 7:9;] and the second, seeing that the Hebrew word for call [though sometimes bearing the meaning, see Isaiah 41:4 ] never so absolutely signifies ‘to call into existence,’ as it must on that interpretation; and he prefers the third: in Isaac, through and in descent from him, shall thy seed be called thy seed: that is, only Isaac’s descendants shall be known as Abraham’s seed.”
