'Be Strong' in the Bible

Say to those who are full of fear, Be strong and take heart: see, your God will give punishment; the reward of God will come; he himself will come to be your saviour.

You who give good news to Zion, get up into the high mountain; you who give good news to Jerusalem, let your voice be strong; let it be sounding without fear; say to the towns of Judah, See, your God!

The Lord will go out as a man of war, he will be moved to wrath like a fighting-man: his voice will be strong, he will give a loud cry; he will go against his attackers like a man of war.

Have no fear, be strong in heart; have I not made it clear to you in the past, and let you see it? and you are my witnesses. Is there any God but me, or a Rock of whom I have no knowledge?

Only in the Lord will Jacob overcome and be strong: together all those who were angry with him will be put to shame and come to destruction.
