'Keep' in the Bible

Which is easier, to say to the paralyzed man, ‘Your sins are forgiven’; or to say, ‘Get up, and pick up your mat and walk’?

Overhearing what was being said, Jesus said to the synagogue official, “Do not be afraid; only keep on believing [in Me and my power].”

He was also saying to them, “You are experts at setting aside and nullifying the commandment of God in order to keep your [man-made] tradition and regulations.

Jesus repeatedly ordered them, saying, “Watch out! Beware of the leaven of the Pharisees and the leaven of Herod.”

Jesus looked around and said to His disciples, “How difficult it will be for those who are wealthy [and cling to possessions and status as security] to enter the kingdom of God!”

Many sternly rebuked him, telling him to keep still and be quiet; but he kept on shouting out all the more, “Son of David (Messiah), have mercy on me!”

And He said to them, “My soul is deeply grieved and overwhelmed with sorrow, to the point of death; remain here and keep watch.”

And He came back and found them sleeping, and He said to Peter, “Simon, are you asleep? Were you unable to keep watch for one hour?

Keep [actively] watching and praying so that you do not come into temptation; the spirit is willing, but the body is weak.”
