It is somewhat remarkable that the prophet Elijah, and John the Baptist, should have been as much alike in dress as they were in their commission. Our dear Lord pointed to John as the Elias of the gospel. If ye will receive it, (said Christ) this is Elias which was for to come. Matthew 11:14. Observe the alarms of a guilty conscience in the case of Ahaziah. His own fears interpreted to him that this must be the servant of the Lord, whose religion he had despised. Like his father, he knew that no prophet of the Lord could prophecy good concerning him, but evil. See 1 Kings 22:8.
2 Kings 1:5-8
5 And when the messengers turned back unto him, he said unto them, Why are ye now turned back?
6 And they said unto him, There came a man up to meet us, and said unto us, Go, turn again unto the king that sent you, and say unto him, Thus saith the LORD, Is it not because there is not a God in Israel, that thou sendest to enquire of Baalzebub the god of Ekron? therefore thou shalt not come down from that bed on which thou art gone up, but shalt surely die.
7 And he said unto them, What manner of man was he which came up to meet you, and told you these words?
8 And they answered him, He was an hairy man, and girt with a girdle of leather about his loins. And he said, It is Elijah the Tishbite.
