19:31-39 Barzillai thought he had done himself honour in doing the king any service. Thus, when the saints shall be called to inherit the kingdom, they will be amazed at the recompence being so very far beyond the service, Mt 25:37. A good man would not go any where to be burdensome; or, will rather be so to his own house than to another's. It is good for all, but especially becomes old people, to think and speak much of dying. The grave is ready for me, let me go and get ready for it.And Barzillai said unto the king,.... In answer to the grateful proposal he made:

how long have I to live; that could not be said with exactness by any; but it might be probably conjectured from the age he was of, and the infirmities that attended him, that he could not live long; it was but a short time he had to be in the world:

that I should go up with the king to Jerusalem? take so long a journey as that, seeing he might die before he got thither; and if he did not, since it could not be thought he should live long, he could not think of it, or judge it advisable at such an age to take such a journey, change his place of abode, and manner of living.
