Final answer:
David said the Lord would bring victory and success to his military campaigns, as seen in instances like 2 Samuel 8:6,14 and support him in battles, ensuring that his enemies fall before him.
Step-by-step explanation:
The query you have regarding what David said the Lord would do is extensive and can be seen through different actions and promises in the scripture. In various passages, we see that the Lord delivered David's enemies into his hands, supporting him in battles.
For instance, 2 Samuel 5:25 states, "And David did as the Lord commanded him, and smote the Philistines." Furthermore, we can see in 2 Samuel 8:6,14, "The Lord gave victory to David wherever he went." This highlights that the Lord would bring about victory and success to David's military campaigns.
Additionally, there are prophetic instances in Ezekiel, like in EZ 6:12-13, where the Lords says through the prophet that there will be consequences for idolatry and rebellion such as sword, famine, and plague.
