After a long time, in the third year of the drought, the word of the LORD came to Elijah: “Go and present yourself to Ahab, and I will send rain upon the face of the earth.”

And it came to pass after many days, that the word of the LORD came to Elijah in the third year, saying, Go, shew thyself unto Ahab; and I will send rain upon the earth.
