They, therefore, "pitch their camp in the valleys." "But the Spirit," it says, "of God strengthened Gideon, and he sounded the trumpet, upon the horn of the trumpet, and called Abiezer after him." The continuity of the exposition, indeed, required a different order, but because we are now speaking not so much to comment on the Scriptures as to console the people concerning those things which have been read, we treat here and there, as they occur, of individual points. "He called," it says, "Abiezer after him," who indeed was nowhere at all. Now "Abiezer" is interpreted as "the help of my father." Therefore Gideon seems to have called upon not some man, but the help of the highest Father. Meanwhile he also sends to summon reinforcements. The peoples come together, and the whole army is gathered to Gideon.
