Nahum 2:1

One who scatters advances against you, O Nineveh. Guard the fortress! Watch the road! Brace yourselves! Summon all your strength!

2 For the LORD will restore the splendor of Jacob like the splendor of Israel, though destroyers have laid them waste and ruined the branches of their vine.

3 The shields of his mighty men are red; the valiant warriors are dressed in scarlet. The fittings of the chariots flash like fire on the day they are prepared, and the spears of cypress have been brandished.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
