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,"
1 Kings 2:1-3
Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places.
Ephesians 6:11-12
