'Pushed' in the Bible

And a messenger hath come in unto Saul, saying, 'Haste, and come, for the Philistines have pushed against the land.'

And Achish saith, 'Whither have ye pushed to-day?' and David saith, 'Against the south of Judah, and against the south of the Jerahmeelite, and unto the south of the Kenite.'

And it cometh to pass, in the coming in of David and his men to Ziklag, on the third day, that the Amalekites have pushed unto the south, and unto Ziklag, and smite Ziklag, and burn it with fire,

we pushed to the south of the Cherethite, and against that which is to Judah, and against the south of Caleb, and Ziklag we burned with fire.'
