Some translations set each line of poetry farther to the right than the rest of the text to make it easier to read. The ULB does this with the poetic song in 29:5.
It is unclear whether David wanted to go into battle with the Philistines. He would have been fighting against Saul, but he also would have been fighting against Israel's soldiers. It is probably best to see that David is conflicted over this issue, but some scholars believe that David planned on turning against the Philistines in the battle.
