I will put] Psalms 18:2. & Psalms 22:30. It is the dutie of man subject to misery and affliction to put his trust in God, and therefore when Christ affirmes of himself (I wil put, &c.) thereby he implies his humane nature subject to misery and affliction. Behold] Isaiah was a type of Christ: hence that which he affirmes of himself, is true of Christ. children] Not onely Isaiah himself was a type of Christ, but his children also were a figure of those whom Christ was to bring unto glory. See Isaiah 8:18.
