Isaiah 6:3

6:3 They called out to one another, “Holy, holy, holy ¹  is the Lord who commands armies! ²  His majestic splendor fills the entire earth!”

Isaiah 6:5

6:5 I said, “Too bad for me! I am destroyed, ³  for my lips are contaminated by sin, ⁴  and I live among people whose lips are contaminated by sin. ⁵  My eyes have seen the king, the Lord who commands armies.” ⁶ 

[6:3]  ¹ tn Some have seen a reference to the Trinity in the seraphs’ threefold declaration, “holy, holy, holy.” This proposal has no linguistic or contextual basis and should be dismissed as allegorical. Hebrew sometimes uses repetition for emphasis. (See IBHS 233-34 §12.5a; and GKC 431-32 §133.k.) By repeating the word “holy,” the seraphs emphasize the degree of the Lord’s holiness. For another example of threefold repetition for emphasis, see Ezek 21:27 (Heb. v. 32). (Perhaps Jer 22:29 provides another example.)

[6:3]  ² tn Perhaps in this context, the title has a less militaristic connotation and pictures the Lord as the ruler of the heavenly assembly. See the note at 1:9.

[6:5]  ³ tn Isaiah uses the suffixed (perfect) form of the verb for rhetorical purposes. In this way his destruction is described as occurring or as already completed. Rather than understanding the verb as derived from דָּמַה (damah, “be destroyed”), some take it from a proposed homonymic root דמה, which would mean “be silent.” In this case, one might translate, “I must be silent.”

[6:5]  ⁴ tn Heb “a man unclean of lips am I.” Isaiah is not qualified to praise the king. His lips (the instruments of praise) are “unclean” because he has been contaminated by sin.

[6:5]  ⁵ tn Heb “and among a nation unclean of lips I live.”

[6:5]  ⁶ tn Perhaps in this context, the title has a less militaristic connotation and pictures the Lord as the ruler of the heavenly assembly. See the note at 1:9.
