Joshua 5:13-15 (NIV)
13 Now when Joshua was near Jericho, he looked up and saw a man standing in front of him with a drawn sword in his hand. Joshua went up to him and asked, “Are you for us or for our enemies?”
14 “Neither,” he replied, “but as commander of the army of the Lord I have now come.” Then Joshua fell facedown to the ground in reverence, and asked him, “What message does my Lord have for his servant?”
15 The commander of the Lord’s army replied, “Take off your sandals, for the place where you are standing is holy.” And Joshua did so.
10 In the same way, I tell you, there is rejoicing in the presence of the angels of God over one sinner who repents.”
10 Finally, be strong in the Lord and in his mighty power. 11 Put on the full armor of God, so that you can take your stand against the devil’s schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace. 16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God.
