Albert Barnes Commentary 2 Kings 4:8

"And it fell on a day, that Elisha passed to Shunem, where was a great woman; and she constrained him to eat bread. And so it was, that as oft as he passed by, he turned in thither to eat bread." — 2 Kings 4:8 (ASV)

And it fell on a day - This original expression, which occurs three times in the narrative (2 Kings 4:11, 18), is also found in Job 1:6, 13; and Job 2:1. The nature of the phrase perhaps supports the view that the author of Kings collected his account of Elisha's miracles from various sources and, in each case, preserved the words of the original writer.

A great woman - That is, “a rich woman.” Compare 1 Samuel 25:2 and 2 Samuel 19:32.
