32 Now Barzillai was a very old man, as much as eighty years old: and he had given the king everything he had need of, while he was at Mahanaim, for he was a very great man. 33 And the king said to Barzillai, Come over with me, and I will take care of you in Jerusalem. 34 And Barzillai said to the king, How much of my life is still before me, for me to go up to Jerusalem with the king? 35 I am now eighty years old: good and bad are the same to me; have meat and drink any taste for me now? am I able to take pleasure in the voices of men or women in song? why then am I to be a trouble to my lord the king? 36 Your servant's desire was only to take the king over Jordan; why is the king to give me such a reward? 37 Let your servant now go back again, so that when death comes to me, it may be in my town and by the resting-place of my father and mother. But here is your servant Chimham: let him go with my lord the king, and do for him what seems good to you. 38 And the king said in answer, Let Chimham go over with me, and I will do for him whatever seems good to you: and whatever your desire is, I will do it for you. 39 Then all the people went over Jordan, and the king went over: and the king gave Barzillai a kiss, with his blessing; and he went back to his place.

(Read 2 Samuel 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, Matthew 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.
