Charles Ellicott Commentary 2 Kings 4:24

"Then she saddled an ass, and said to her servant, Drive, and go forward; slacken me not the riding, except I bid thee." — 2 Kings 4:24 (ASV)

Then she saddled an ass. — And she saddled the ass — that is, which the young man brought, and probably saddled at her bidding.

Slack not your riding for me. — Literally, do not restrain me from riding — that is, do not stop, or slacken speed. A halt for rest might naturally be taken, as the distance was considerable.
