'Be Strong' in the Bible

Now pay attention to all the commandments I am giving you today, so that you may be strong enough to enter and possess the land where you are headed,

Be strong and courageous! Do not fear or tremble before them, for the Lord your God is the one who is going with you. He will not fail you or abandon you!"

Then Moses called out to Joshua in the presence of all Israel, "Be strong and courageous, for you will accompany these people to the land that the Lord promised to give their ancestors, and you will enable them to inherit it.

and the Lord commissioned Joshua son of Nun, "Be strong and courageous, for you will take the Israelites to the land I have promised them, and I will be with you."
