The sword of the Lord, and of Gideon— Though the word sword is not in the Hebrew in this place, yet, as it is read in the 20th verse, our translators have very properly added it. It is evident, says Houbigant, that in these words Gideon alludes to the interpretation of the dream given in the 14th verse. As the three hundred men were divided into three companies, detached to different parts of the Midianitish camp, Gideon, as appears from the next verse, was attended only by one hundred men.
