Hebrews 2:13

And again, I will put my trust in him. And again, Behold I and the children which God hath given me.

I will put my trust in him - from Septuagint [ pepoithoos (G3982) esomai (G1510) ep' (G1909) autoo (G846)], Isaiah 8:17, which immediately precedes "Behold I and the children," etc. The objection is, the following words, "and again," usually introduce a new quotation; whereas these two are parts of one passage. However, the two clauses express distinct ideas. "I will put my trust in Him" expresses His filial confidence in His Father, to whom He flees in sufferings, and is not disappointed; which His believing brethren imitate, trusting solely in the Father through Christ, not in their own merits. 'Christ exhibited this "trust," not for Himself, for He and the Father are one, but for His people' (Hebrews 2:16). Each fresh aid given assured Him, as it does them, of further aid, until the complete victory was obtained over hell (Philippians 1:6) (Bengel).

Behold I and the children ... (Isaiah 8:18.) "Sons" (Hebrews 2:10), "brethren" (Hebrews 2:12), "children" imply His right and property in them from everlasting. He calls them "children" of God, though not yet in being, but considered so in His purpose; and presents them before the Father, who has given Him them, to be glorified with Himself. Isaiah (meaning 'salvation of Yahweh') typically represented Messiah, at once Father and Son, Isaiah and Immanuel (Isaiah 9:6). Isaiah and his children rely, not like Ahaz and the Jews on the Assyrian king, against the confederacy of Pekah of Israel and Rezin of Syria, but on Yahweh. He then foretells the deliverance of Judah by God, in language realized only in the far greater deliverance performed by Messiah. Christ, the antitypical Prophet, instead of the human confidences of His age, Himself, and GOD THE father's children (who are therefore His children, so antitypical to Isaiah's, though regarded also as His "brethren:" cf. Isaiah 9:6, "Father;" and "His seed," Isaiah 53:10), led by Him, trust wholly in God for salvation. The official words and acts of the prophets find their antitype in the Great Prophet (Revelation 19:10); as His kingly office is antitypical to that of the theocratic kings, and His priestly office to the Aaronic priesthood.
