Charles Ellicott Commentary Psalms 105:37

"And he brought them forth with silver and gold; And there was not one feeble person among his tribes." — Psalms 105:37 (ASV)

Feeble person. —Literally, stumbling. (Compare to Isaiah 5:27: None shall be weary or stumble among them, i.e., none unfit for the march and military duty.)
