John Gill Commentary Judges 8:4

"And Gideon came to the Jordan, [and] passed over, he, and the three hundred men that were with him, faint, yet pursuing." — Judges 8:4 (ASV)

And Gideon came to Jordan, and passed over .
&c.] That river; (See Gill on Judges 7:25) he and three hundred men that were with him, at the defeat of the Midianites in the valley of Jezreel; so that neither at that nor in the pursuit of them hitherto, has he lost one man:

faint, yet pursuing [them] :
they were faint with being up all night, and continually blowing their trumpets; and had been upon the pursuit of their enemies ever since the defeat; and yet, though they were so faint, they did not leave off the pursuit, but were eager at it.
