At 99 Abraham was told that he would have another child Isaac. Isaac was certainly a young man when Abraham took him on a strenuous trip to the hills of Moriah, a place where “God” showed him. (this region was where David bought the threshing floor to build an altar for sacrifice to stop the plague upon Israel. It was also the same region that Jesus was crucified!). Abraham lived to be 175 years old! So he obviously was vigorous and could still do a lot of physical work!
