Jeremiah
1 Kings 18:7BSB·traditional attribution

Now as Obadiah went on his way, Elijah suddenly met him. When Obadiah recognized him, he fell facedown and said, “Is it you, my lord Elijah?”

Matthew Henry Presbyterian @wholebiblehenry

In these verses we find, I. The sad state of Israel at this time, upon two accounts: - 1. Jezebel cut off the prophets of the Lord (Kg1 18:4), slew them, Kg1 18:13. Being an idolater, she was a persecutor, and made Ahab one.

And as Obadiah was in the way,.... In his district, making his observations: behold, Elijah met him: where is not said; but he was, no doubt, upon the road from Zarephath to Samaria: and he knew him that is, Obadiah knew Elijah, having seen him at Ahab's court before he absconded: and fell on his face, and said, art thou that my lord Elijah?

Jamieson-Fausset-Brown Reformed @jfbcommentary

Obadiah was in the way . . . Elijah met him--Deeming it imprudent to rush without previous intimation into Ahab's presence, the prophet solicited Obadiah to announce his return to Ahab. The commission, with a delicate allusion to the perils he had already encountered in securing others of God's servants, was, in very touching terms, declined, as unkind and peculiarly hazardous.
