'Resolve' in the Bible

The officials of Issachar were with Deborah, as was the tribe of Issachar and Barak. They rushed out into the valley at his heels along with divisions from Reuben's army. Great was their resolve of heart!

Zedekiah rebelled against King Nebuchadnezzar, who had made him swear allegiance in the name of God. Instead, he stiffened his resolve, and hardened his heart, and would not return to the LORD God of Israel.
