In this latter category, here are the two best ones, in my opinion:
- Hebrews 12:12 Therefore, strengthen your feeble arms and weak knees.
- Deuteronomy 33:27 The eternal God is your refuge, and underneath are the everlasting arms. He will drive out your enemy before you, saying, 'Destroy him!'
For Deuteronomy 33:27, the God's Word Translation (which is less a translation, and more a paraphrasing) has the best version: "The eternal God is your shelter, and his everlasting arms support you. He will force your enemies out of your way and tell you to destroy them." I imagine if I were facing a bunch of huge guys wanting to tackle me, this verse would feel pretty darn inspiring.
