Isaiah 6:5

Woe - An expression of grief or indignation.

Wo is me! for I am undone - נדמיתי nidmeythi, I am become dumb. There is something exceedingly affecting in this complaint. I am a man of unclean lips; I cannot say, Holy, holy, holy! which the seraphs exclaim. They are holy; I am not so: they see God, and live; I have seen him, and must die, because I am unholy. Only the pure in heart shall see God; and they only can live in his presence for ever, Reader, lay this to heart; and instead of boasting of thy excellence, and trusting in thy might, or comforting thyself in thy comparative innocence, thou wilt also be dumb before him, because thou hast been a man of unclean lips, and because thou hast still an unclean heart.

I am undone "I am struck dumb" - נדמיתי nidmeythi, twenty-eight MSS. (five ancient) and three editions. - I understand it as from דום dum or דמם damam, silere, "to be silent;" and so it is rendered by the Syriac, Vulgate, Symmachus, and by some of the Jewish interpreters, apud Sal. b. Melec. The rendering of the Syriac is תויר אני tavir ani, stupens, attonitus sum, "I am amazed." He immediately gives the reason why he was struck dumb: because he was a man of polluted lips, and dwelt among a people of polluted lips, and was unworthy, either to join the seraphim in singing praises to God, or to be the messenger of God to his people. Compare Exodus 4:10; Exodus 6:12; Jeremiah 1:6.

Wo is me! - That is, I am filled with overwhelming convictions of my own unworthiness, with alarm that I have seen Yahweh.

For I am undone - Margin, 'Cut off.' Chaldee, 'I have sinned.' Septuagint, 'I am miserable, I am pierced through.' Syriac, 'I am struck dumb.' The Hebrew word may sometimes have this meaning, but it also means "to be destroyed, to be ruined, to perish;" see Hosea 10:15; Zephaniah 1:2; Hosea 4:6; Isaiah 15:1. This is probably the meaning here, 'I shall be ruined, or destroyed.' The reason of this, he immediately states.

A man of unclean lips - This expression evidently denotes that he was a "sinner," and especially that he was unworthy either to join in the praise of a God so holy, or to deliver a message in his name. The vision; the profound worship of the seraphim; and the attendant majesty and glory, had deeply impressed him with a sense of the holiness of God, and of his own unfitness either to join in worship so holy, or to deliver the message of so pure a God. A similar effect is recorded in reference to Abraham; Genesis 18:27; see also Exodus 4:10, Exodus 4:12; Jeremiah 1:6. A deep consciousness of guilt, in view of the holiness and majesty of God, is also described by Job:

I have heard of thee by the hearing of the ear

But now mine eye seeth thee.

Wherefore I abhor myself,

And repent in dust and ashes.

6:5 l am - I am a great sinner, as many other ways, so particularly by my lips. I am an unclean branch of an unclean tree; besides my own uncleanness, I have both by my omissions and commissions involved myself in the guilt of their sins. Have seen - The sight of this glorious and holy God gives me cause to fear that he is come to judgment against me.
