Boyd’s Bible Dictionary:

Hebrew offensive weapons were the sword (1 Sam. 17:51; 25:1351Therefore David ran, and stood upon the Philistine, and took his sword, and drew it out of the sheath thereof, and slew him, and cut off his head therewith. And when the Philistines saw their champion was dead, they fled. (1 Samuel 17:51)
13And David said unto his men, Gird ye on every man his sword. And they girded on every man his sword; and David also girded on his sword: and there went up after David about four hundred men; and two hundred abode by the stuff. (1 Samuel 25:13)
; 2 Sam. 20:88When they were at the great stone which is in Gibeon, Amasa went before them. And Joab's garment that he had put on was girded unto him, and upon it a girdle with a sword fastened upon his loins in the sheath thereof; and as he went forth it fell out. (2 Samuel 20:8); Judg. 3:1616But Ehud made him a dagger which had two edges, of a cubit length; and he did gird it under his raiment upon his right thigh. (Judges 3:16)); spear (1 Sam. 17:77And the staff of his spear was like a weaver's beam; and his spear's head weighed six hundred shekels of iron: and one bearing a shield went before him. (1 Samuel 17:7); 2 Sam. 2:23; 23:823Howbeit he refused to turn aside: wherefore Abner with the hinder end of the spear smote him under the fifth rib, that the spear came out behind him; and he fell down there, and died in the same place: and it came to pass, that as many as came to the place where Asahel fell down and died stood still. (2 Samuel 2:23)
8These be the names of the mighty men whom David had: The Tachmonite that sat in the seat, chief among the captains; the same was Adino the Eznite: he lift up his spear against eight hundred, whom he slew at one time. (2 Samuel 23:8)
); bow and arrow [ARCHERY]; sling (2 Kings 3:2525And they beat down the cities, and on every good piece of land cast every man his stone, and filled it; and they stopped all the wells of water, and felled all the good trees: only in Kir-haraseth left they the stones thereof; howbeit the slingers went about it, and smote it. (2 Kings 3:25)); battle-ax (Jer. 51:2020Thou art my battle axe and weapons of war: for with thee will I break in pieces the nations, and with thee will I destroy kingdoms; (Jeremiah 51:20)). Among defensive armor were breastplates, cuirasses, coats of mail, helmets, greaves, habergeons, shields, bucklers (1 Sam. 17:5-75And he had an helmet of brass upon his head, and he was armed with a coat of mail; and the weight of the coat was five thousand shekels of brass. 6And he had greaves of brass upon his legs, and a target of brass between his shoulders. 7And the staff of his spear was like a weaver's beam; and his spear's head weighed six hundred shekels of iron: and one bearing a shield went before him. (1 Samuel 17:5‑7); 2 Chron. 26:1414And Uzziah prepared for them throughout all the host shields, and spears, and helmets, and habergeons, and bows, and slings to cast stones. (2 Chronicles 26:14)).
