إشعياء ٦:٨

When Isaiah had been thus absolved, the true object of the heavenly scene was made apparent."Then I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then I said, Behold me here; send me!" The plural "for us" (lânu) is not to be accounted for on the ground that, in a case of reflection or self-consultation, the subject also stands as the object in antithesis to itself (as Hitzig supposes); nor is it a pluralis majestatis, as Knobel maintains; nor is the original abstract signification of the plural hinted at, as Meier thinks. The plural is no doubt used here with reference to the seraphim, who formed, together with the Lord, one deliberative council (sōd kedoshim, Psa 89:8), as in Kg1 22:19-22; Dan 4:14, etc.; just as, from their very nature as "sons of God" (b'nē Hâ-elohim), they made one family with God their Creator (vid., Eph 3:15), all linked so closely together that they themselves could be called Elohim, like God their Creator, just as in Co1 12:12 the church of believers is called Christos, like Christ its head. The task for which the right man was sought was not merely divine, but heavenly in the broadest sense: for it is not only a matter in which God Himself is interested, that the earth should become full of the glory of God, but this is also an object of solicitude to the spirits that minister unto Him. Isaiah, whose anxiety to serve the Lord was no longer suppressed by the consciousness of his own sinfulness, no sooner heard the voice of the Lord, than he exclaimed, in holy self-consciousness, "Behold me here; send me." It is by no means a probable thing, that he had already acted as a messenger of God, or held the office of prophet. For if the joy, with which he offered himself here as the messenger of God, was the direct…

Hitherto, it should seem, Isaiah had prophesied as a candidate, having only a virtual and tacit commission; but here we have him (if I may so speak) solemnly ordained and set apart to the prophetic office by a more express or explicit commission, as his work grew more upon his hands: or perhaps, having seen little success of his ministry, he began to think of giving it up; and therefore God saw fit to renew his commission here in this chapter, in such a manner as might excite and encourage his zeal and industry in the execution of it, though he seemed to labour in vain. In this chapter we have, I. A very awful vision which Isaiah saw of the glory of God (Isa 6:1-4), the terror it put him into (Isa 6:5), and the relief given him against that terror by an assurance of the pardon of his sins (Isa 6:6, Isa 6:7). II. A very awful commission which Isaiah received to go as a prophet, in God's name (v. 8), by his preaching to harden the impenitent in sin and ripen them for ruin (v. 9-12) yet with a reservation of mercy for a remnant, (v. 13). And it was as to an evangelical prophet that these things were shown him and said to him.

6:8 Who will go for us? The Lord spoke in the presence of his angels, the heavenly council (see also 1 Kgs 22:19-22; Jer 23:18, 22). • Here I am: The prophet was so overcome by the grace of God in cleansing him that he willingly committed himself to a lifetime of ministry.
