"When the time drew near for David to die, he gave a charge to Solomon his son. 'I am about to go the way of all the earth,' he said. 'So be strong, show yourself a man, and observe what the Lord your God requires: Walk in his ways, and keep his decrees and commands, his laws and requirements, as written in the Law of Moses, so that you may prosper in all you do and wherever you go, and that the Lord may keep his promise to me: "If your descendants watch how they live, and if they walk faithfully before me with all their heart and soul, you will never fail to have a man on the throne of Israel."'" NIV translation
Before David died, he urged Solomon to stand up and be a man and he went on to explain what that means. He was speaking of being a man of God and following Him. David had messed up in his life but he was still known as a great man of God. He also reminded Solomon of the fact that God promised him that his family line would remain on the throne as long as they were faithful to Him.
We see that he urges Solomon to walk faithfully with all his "heart and soul" and not just going through the motions and saying it.
It seems like we need more fathers to explain this to their sons today. Many young men have gotten the idea that being a man is all about the size of your bank account, the number of women you can get, or your street reputation. For more on this, check out our Measure of a Man devotion.
"'Now you yourself know what Joab son of Zeruiah did to me - what he did to the two commanders of Israel's armies, Abner son of Ner and Amasa son of Jether. He killed them, shedding their blood in peacetime as if in battle, and with that blood stained the belt around his waist and the sandals on his feet. Deal with him according to your wisdom, but do not let his gray head go down to the grave in peace.'" NIV translation
What had Joab done? He had supported Adonijah when he tried to make himself king. He had also killed Abner and Amasa because he did not want them to replace him as Israel's military commander. David urges Solomon to deal with him at the proper time.
