It becomes He

In Habakkuk 2:3 we read, "For the revelation awaits an appointed time; it speaks of the end and will not prove false. Though it linger, wait for it; it will certainly come and will not delay." It seems clear to me that this refers to the revelation that was given to Habakkuk by the Lord Himself. However, the writer of Hebrews quotes this verse in Hebrews 10:37 and he changes the pronoun to "he". "For in just a very little while, He who is coming will come and will not delay." The writer of Hebrews sees this as a prophecy of the coming of the Messiah. I know that some interpret the meaning of Habakkuk differently but to me the writer of Hebrews makes it very clear.
