2 Samuel 19:32

Now Barzillai was a very aged man, [even] fourscore years old,.... Which was ten years beyond the common term of man's life, and reckoned a very great age in David's time, and has been ever since, and still is, see Psalms 90:10;

and he had provided the king of sustenance while he lay at Mahanaim: had supported him and his family, furnished him with provisions, and all the necessaries of life, during his stay there:

for he [was] a very great man; in wealth and riches, and was a very liberal man, and a man of great wisdom and good sense; and very probably was a man of great grace, which taught him his duty to his prince, and influenced him to show mercy to him in distress.
