What does 1 Samuel 27:1 mean?

And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should escape into the land of the Philistines; and Saul will despair of me, to seek me any more in all the borders of Israel: so shall I escape out of his hand.

And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should speedily escape into the land of the Philistines; and Saul shall despair of me, to seek me any more in any coast of Israel: so shall I escape out of his hand.

And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should escape into the land of the Philistines; and Saul will despair of me, to seek me any more in all the borders of Israel: so shall I escape out of his hand.

And David said to himself, Some day death will come to me by the hand of Saul: the only thing for me to do is to get away into the land of the Philistines; then Saul will give up hope of taking me in any part of the land of Israel: and so I may be able to get away from him.

And David saith unto his heart, `Now am I consumed one day by the hand of Saul; there is nothing for me better than that I diligently escape unto the land of the Philistines, and Saul hath been despairing of me--of seeking me any more in all the border of Israel, and I have escaped out of his hand.'

And David said in his heart: I shall one day or other fall into the hands of Saul: is it not better for me to flee, and to be saved in the land of the Philistines, that Saul may despair of me, and cease to seek me in all the coasts of Israel? I will flee then out of his hands.

And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should speedily escape into the land of the Philistines; and Saul will despair of me to seek me any more within all the limits of Israel, and I shall escape out of his hand.
