'Equip' in the Bible

“For behold, I will stir up and bring up against BabylonAn assembly of great nations from the north country.They will equip themselves and set up the battle lines against her;From there she will be taken captive.Their arrows will be like an expert warriorWho will not return empty-handed.

equip you with every good thing to carry out His will and strengthen you [making you complete and perfect as you ought to be], accomplishing in us that which is pleasing in His sight, through Jesus Christ, to whom be the glory forever and ever. Amen.
