Habakkuk - First Chronicles

Habakkuk describes beheading the wicked, which is Saul in First Chronicles.

Saul's Beheading

Habakkuk First Chronicles

36 Habakkuk 3:13
13You went forth to save your people and to save your anointed; you cut off the head out of the house of the wicked, you have laid him bare from his foundations, even to the neck forever.

37 First Chronicles 10:8-10
8And it came to pass on the next day, when the Philistines came to strip the slain, they found Saul and his 3 sons fallen on mount Gilboa.
9And they cut off their heads, stripped them of their armour, and sent them to the land of the Philistines, throughout the towns and cities and provinces to carry the good news to their idols and to their people;
10and they put their garments and their armour in the house of their idols, and hung their bodies by the wall in the house of Dagon.

Habakkuk describes Yahvah going forth to deliver his anointed. The term anointed refers at times to the reigning king of Israel. Recall that David was anointed king by Samuel, but had to wait his turn while preserving his life on the run from Saul. Eventually Saul is defeated by the Philistines and even beheaded after falling on his own sword. Habakkuk adds, by way of context, that this was Yahvah's way of delivering David from wicked Saul.

(This link in the Book Chain requires advancing to the first story in First Chronicles, which happens in chapter 10, when Saul goes to battle the Philistines. Trying to link Habakkuk to the names at the beginning of First Chronicles is fruitless, and clearly not the design for how these books link given the way Habakkuk links so nicely to the first story after the names.)
