1 Samuel 4-6
Once Israel entered the promised land, other than the battle of Jericho there is no mention of Israel taking the Ark of the covenant into battle. It appears that the Tabernacle was erected in Gilgal where Israel made their camp while they conquered the land (Joshua 5:10). Later it was moved to Shiloh by Joshua (Joshua 18:1), where it stayed for hundreds of years until the end of Eli’s priesthood when it was taken by the Philistines after they won the battle with Israel. Whoever made the decision to bring the ark into the battle is unknown but it was a very stupid decision. The prophesied judgment upon Eli’s house by an unnamed prophet and by a very young Samuel was fulfilled. The two ungodly sons of Eli were slain, and Eli, after hearing the news of the death of his sons, fell backward and broke his neck and he died and the daughter in law of Eli also died giving birth to his son’s son. The ark was captured by the Philistines and was in their hands for seven months. The Philistines though, suffered the entire time the Ark was in their hands and because of that suffering they could not get rid of the ark fast enough. The ark was finally brought to Kirjath-jearim within Israel where it rested for well over 40 years, until the time that David brought it up to Jerusalem.
In Luke 12:35 Jesus tells us to have our loins girded about. He is not speaking primarily about our physical loins but the loins of our mind being wrapped with the word of God (1 Peter 1:13), which is part of our spiritual armor (Ephesians 6:14). Jesus goes on to say we are to have our lights burning. Matthew wrote that Jesus said that we are the light of the world, and we are to let our lights shine before men (Matthew 5:14-16). The light that we shine is the light of the glory of God in the face of Jesus Christ (2 Corinthians 4:6). Hallelujah!
