And the Philistines hearing that David was anointed king over all Israel, went all up to seek him: and David heard of it, and went out against them.

And the Philistines hear that David hath been anointed for king over all Israel, and all the Philistines go up to seek David, and David heareth, and goeth out before them.

And when the Philistines had news that David had been made king over all Israel, they went up in search of David, and David, hearing of it, went out against them.

And when the Philistines heard that David was anointed king over all Israel, all the Philistines went up to seek David; and David heard of it, and went out to meet them.

Then, hearing that David had been anointed as king over all of Israel, all the Philistines ascended so that they might seek him. But when David had heard of it, he went out to meet them.

The Philistines went up to seek David - See on 2-Samuel 5:17 (note).

HIS VICTORIES OVER THE PHILISTINES. (1-Chronicles 14:8-17)
all the Philistines went up to seek David--in the hope of accomplishing his ruin (for so the phrase is used, 1-Samuel 23:15; 1-Samuel 24:2-3) before his throne was consolidated. Their hostility arose, both from a belief that his patriotism would lead him, ere long, to wipe out the national dishonor at Gilboa, and by fear, that in any invasion of their country, his thorough knowledge of their weak points would give him superior advantages. They resolved, therefore, to surprise and crush him before he was fairly seated on his throne.
