Verse 13 These expressions seem to be taken from Hebrews 2:13; Isaiah 8:18. Considered as language used by the Messiah, they show a feeling of dependence on God, characteristic of the human condition, thus conspiring with the other considerations presented in this passage, (Hebrews 2:10-18,) to show that the promised Messiah, according to the representations of the Old Testament, was to share in his own person the nature of those whom he came to redeem.
