'Pray' in the Bible

and having taken leave of them, he went away to the mountain to pray.

and pray ye that your flight may not be in winter,

Take heed, watch and pray, for ye have not known when the time is;

And they come to a spot, the name of which is Gethsemane, and he saith to his disciples, 'Sit ye here till I may pray;'

Watch ye and pray, that ye may not enter into temptation; the spirit indeed is forward, but the flesh weak.'
