Charles Ellicott Commentary Joshua 14:11

"As yet I am as strong this day as I as in the day that Moses sent me: as my strength was then, even so is my strength now, for war, and to go out and to come in." — Joshua 14:11 (ASV)

As yet I am as strong this day ... —But by Joshua 13:1, Joshua had aged. Yet Joshua died at the age of 110, only 25 years older than Caleb was at this time. They were contemporaries. But the far greater responsibility lying upon Joshua (with a possible difference of temperament) may very naturally account for the one man’s having aged so much more rapidly than the other.
