Passage
And it shall come to pass, that him that escapeth from the sword of Hazael shall Jehu slay; and him that escapeth from the sword of Jehu shall Elisha slay.
And it shall come to pass, that him that escapeth from the sword of Hazael shall Jehu slay; and him that escapeth from the sword of Jehu shall Elisha slay.
1 Kings 19:15 And Jehovah said unto him, Go, return on thy way to the wilderness of Damascus: and when thou comest, thou shalt anoint Hazael to be king over Syria;
1 Kings 19:16 and Jehu the son of Nimshi shalt thou anoint to be king over Israel; and Elisha the son of Shaphat of Abel-meholah shalt thou anoint to be prophet in thy room.
1 Kings 19:17 And it shall come to pass, that him that escapeth from the sword of Hazael shall Jehu slay; and him that escapeth from the sword of Jehu shall Elisha slay.
1 Kings 19:18 Yet will I leave [me] seven thousand in Israel, all the knees which have not bowed unto Baal, and every mouth which hath not kissed him.
1 Kings 19:19 So he departed thence, and found Elisha the son of Shaphat, who was plowing, with twelve yoke [of oxen] before him, and he with the twelfth: and Elijah passed over unto him, and cast his mantle upon him.
The verse centers on "shall", "come", "pass", "escapeth", "sword", "hazael", and "jehu". It is saying that the verse draws attention to "shall" and "come", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "and Jehu the son of Nimshi shalt..." into verse 18's "Yet will I leave me seven thousand...", so "shall" and "come" belong inside that flow. In 1 Kings context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "shall" and "come" with trust shaped by these words, not by a vague optimism outside the passage.
