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?
thus doing him honour and reverence both by words and gesture, as being an extraordinary prophet of the Lord.
