David begins this psalm with a pledge to be steadfast in heart in his praise for the Lord. He will use the lute and harp, and he will sing. Why? Because His mercy is great and His truth reaches the clouds. He then asks the Lord to to deliver him. He then prophetically speaks of the Lord’s conquests through Israel over the lands of Shechem, the Valley of Succoth, Gilead, Mannasseh, Ephraim, Judah, Moab, Edom, and Philistia. While some of these will be conquests of the Lord for His service, the others are to be conquered for their sinfulness to destruction. David then asks who will lead him in this conquest, and surmises that it is God Himself who will lead him into battle.
12 Give us help from trouble,
For the help of man is useless.
13 Through God we will do valiantly,
For it is He who shall tread down our enemies.
David knew that the odds in battle can be swayed quickly and decisively depending on the allies you bring with you into battle. Nations would turn to Egypt, then the Assyrians or the Babylonians, at the peak of their military dominance. But, in this psalm, David makes it clear that He will trust in the help of the Lord. In whom do we trust? With whom shall we cast our lot? Who gets our trust? Take a page from the playbook of David and trust the Lord to give you the victory over your enemies and over your problems. When you trust the Lord, you reach the place of contentment and trust more quickly. You can believe for yourself and others. Trust in the Lord!
