Matthew Henry, An Exposition of the Old and New Testament (1828)
“ He had mentioned it as Shem's honour, that he was the father of the Hebrews; but lest Japheth's seed should therefore be looked upon as for ever shut out from the church, he here reminds us that he was the brother of Japheth, not in birth only, but in blessing, for Japheth was to dwell in the tents of Shem. Note, (1.) Those are brethren in the best manner, that are so by grace, and that meet in the covenant of God, and in the communion of saints. (2.) God, in dispensing his grace, does not go by seniority, but the younger sometimes gets the start of the elder in coming into the church ”
