1 Kings 1:1

Now King David was old - He was probably now about sixty-nine years of age. He was thirty years old when he began to reign, reigned forty, and died in the seventieth year of his age, 2 Samuel 5:4 , and 1 Kings 2:11 ; and the transactions mentioned here are supposed to have taken place about a year before his death.

But he gat no heat - Sixty-nine was not an advanced age; but David had been exhausted with various fatigues, and especially by family afflictions, so that he was much older in constitution than he was in years. Besides he seems to have labored under some wasting maladies, to which there is frequent reference in the Psalms.
