'Armor' in the Bible

Now the day came that Jonathan, the son of Saul, said to the young man who was carrying his armor, “Come and let us cross over to the Philistines’ garrison that is on the other side.” But he did not tell his father.

Then Jonathan said to the young man who was carrying his armor, “Come and let us cross over to the garrison of these uncircumcised; perhaps the Lord will work for us, for the Lord is not restrained to save by many or by few.”

Then Saul clothed David with his garments and put a bronze helmet on his head, and he clothed him with armor.

David girded his sword over his armor and tried to walk, for he had not tested them. So David said to Saul, “I cannot go with these, for I have not tested them.” And David took them off.

Jonathan stripped himself of the robe that was on him and gave it to David, with his armor, including his sword and his bow and his belt.
