Then said I, Woe is me. — The cry of the prophet expresses the normal result of man’s consciousness of contact with God. So Moses “hid his face, for he was afraid to look upon God” (Exodus 3:6). So Job “abhorred himself and repented in dust and ashes” (Job 42:6). So Peter fell down at his Lord’s feet, and cried, “Depart from me, for I am a sinful man, O Lord” (Luke 5:8). Man at such a time feels his nothingness in the presence of the Eternal, his guilt in the presence of the All-holy. No man can see God and live. (Comp. also 1 Samuel 6:20.)
I am a man of unclean lips. — The prophet’s words present at once a parallel and a contrast to those of Moses in Exodus 4:10. The Lawgiver feels only, or chiefly, his want of the gift of utterance which was needed for his work. With Isaiah the dominant thought is that his lips have been defiled by past sins of speech. How can he join in the praises of the seraphim with those lips from which have so often come bitter and hasty words, formal and ceremonial prayers? (Comp. James 3:2; James 3:9). His lips are “unclean” like those of one stricken, as Uzziah had been, by leprosy (Leviticus 13:45). He finds no comfort in the thought that others are as bad as he is, that he “dwells in the midst of a people of unclean lips.” Were it otherwise, there might be some hope that influence from without might work his purification. As it is, he and his people seem certain to sink into the abyss. To “have seen the King, the Lord of hosts,” was in such a case simply overwhelming (Exodus 33:20).
