Joshua 14:9

9. And Moses swear on that day, etc Here, then, is one fruit of the embassy honestly and faithfully performed — to gain possession of an inheritance of which the whole people is deprived. For although long life is justly accounted one of the mercies of God, the end proposed by it is here added, viz., that Caleb may obtain the inheritance which is denied to others. This was no ordinary privilege. He next extols the faithfulness of God in having prolonged his life, and not only so, but supplied vigor and strength, so that though he was now above eighty years of age, he was not a whit feebler than when in the flower of his youth. Others, too, had a green old age, but they were few in number, and then in their case there was not added to the even tenor of their days a manly vigor, remaining wholly unimpaired up to their eighty-fifth year. For he lays claim not only to the skill and valor of a leader, but also to the physical strength of a soldier.

He next adds the other offices and actions of his life. For to go out and in is equivalent in Hebrew to the observance and execution of all parts of our duty. And this Caleb confirms by fact, when he demands it as his task to assail and expel the giants. He is not, however, elated by stolid pride to a confident assurance of victory, but hopes for a prosperous event from the assistance of God. There seems, indeed, to be an incongruous expression of doubt in the word Perhaps, as if he were begirding himself fortuitously for the fight. Those expositors who think that he is distrusting himself from a feeling of modesty and considering his own weakness, say something to the point, but do not say the whole. They certainly omit what is of principal import, viz., that this Perhaps refers to the common feelings which men would entertain on taking a view of the actual state of matters.
