What does Psalm 9:14 mean?

Having prayed for deliverance from his enemies (Psalm 9:13), David anticipates praising the Lord in the tabernacle at Jerusalem for rescuing him. For David, the concepts of deliverance and praise are closely linked.

Believers should always praise the Lord for His protection and care. Unfortunately, a person may be quick to pray for deliverance from trouble, but slow to praise the Lord when He answers his prayer. Ten lepers met Jesus when He entered a village. They stood at a distance and shouted: "Jesus, Master, have mercy on us" (Luke 17:13). At Jesus' command, the lepers set out to show themselves to the priests. As they were on their way, their leprosy left them; they were healed. However, only one of the ten returned to Jesus to thank Him. Jesus asked, "Were not ten cleansed? Where are the nine?" (Luke 17:17). Ingratitude is sinful. Paul tells the believers at Thessalonica, "Give thanks in all circumstances; for this is the will of God in Christ Jesus for you" (1 Thessalonians 5:18).
