Isaiah 8:18

Behold, I, and the children whom the Lord hath given me,.... These are the words of Christ, as is clear from Heb 2:13 who, upon the prophet's declaring his resolution to look and wait for him, presents himself and his children to him, as if he was actually come, or else continues his discourse from the preceding verse; for these are not the words of the prophet, speaking of himself and his natural children, Shearjashub and Mahershalalhashbaz; nor of his spiritual children, his disciples, called sometimes the sons of the prophets; but of Christ, who has a seed, a spiritual offspring, to whom he stands in the relation of a father, Isa 9:6 and who are given him of God, in the covenant of grace; for whose sake he partook of flesh and blood, and died to gather them together, being scattered abroad; and redeemed them, that they might receive the adoption of children; and who, being regenerated, believe in him: these were from eternity given unto him, to be his seed and offspring, his spouse, his sheep, his portion, and inheritance; in virtue of which they are brought unto him, and received by him in time in effectual calling; which gift of them to Christ is an instance of the Father's love to him, and of distinguishing grace to them.
