John Gill 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; Her servant did it by her order:

and said to her servant, drive, and go forward; make all the haste he could:

slack not your riding for me, except I bid you; do not be afraid of riding too fast for me; if you do, I will tell you; till then, keep on a good pace:

Abarbinel says she walked afoot all the way, and ordered the man not to slacken his pace in riding for her, unless she called to him; and the Targum seems to favour this sense, ``do not press me to ride unless I call to you;''

so that the ass was for Elijah to ride on; but one would think, that, as she was in haste, quicker dispatch would be made by her riding than by walking, see (2 Kings 4:22) .
