Isaac and Isaac's son Jacob are mentioned here as carrying on one line of Abraham's traditions. The other line was carried on by Isma'il, who is mentioned independently five verses lower down, as his line got special honour in the Holy Prophet of Islam. That is why his mention comes after that of Moses. Cf. xxi. 72.
