2 Samuel 8:11 Which also king David did dedicate to the Lord, with the silver and gold that he had dedicated of all the nations which he subdued.
Because of David’s faithfulness to the Lord and trust in Him, with God’s help he was able to smite the nearby enemy nations and subdue them. God fulfilled His promise by helping David defeat the opposing nations. Along with the long time nemesis, the Philistines, David smote the Moabites, the Syrians, and the Edomites, and took much plunder of silver and gold and brass.
As an expression of thanksgiving and giving credit to God, David dedicated the gold, silver, and brass he had taken to the Lord. Dedicating the plunder was David’s way of humbly thanking God, proclaiming that it was not by his own strength or good works that he had success, wealth, and victory, but it is the Lord who gave it all out of grace.
Jesus Christ has given to us great spiritual victory over our enemies. He has granted to us life and health and material goods. He gets all the credit and all the glory. We are humble, powerless, weak beggars. Therefore, we respond by dedicating to Him our time, talents, and treasure. Every time we give to the Lord we are acknowledging that all we are and all we have comes fro Him. Thus our tithe is a token of thanks to the Lord for who He is, for what He has done, and for His abundant blessing. God dedicated his life to us; we dedicate our lives to Him.
