'Contend' in the Bible

contend not with them; for I will not give you of their land, no, not so much as for the sole of the foot to tread on; because I have given mount Seir unto Esau for a possession.

And Jehovah said unto me, Vex not Moab, neither contend with them in battle; for I will not give thee of his land for a possession; because I have given Ar unto the children of Lot for a possession.

and when thou comest nigh over against the children of Ammon, vex them not, nor contend with them; for I will not give thee of the land of the children of Ammon for a possession; because I have given it unto the children of Lot for a possession.

Rise ye up, take your journey, and pass over the valley of the Arnon: behold, I have given into thy hand Sihon the Amorite, king of Heshbon, and his land; begin to possess it, and contend with him in battle.
