Revelation 9:17

9:17 Now this is what the horses and their riders looked like in my vision: The riders had breastplates that were fiery red, dark blue, and sulfurous yellow in color. The heads of the horses looked like lions’ heads, and fire, smoke, and sulfur came out of their mouths.

Job 40:18

40:18 Its bones are tubes of bronze,

its limbs like bars of iron.

Job 41:23-30

41:23 The folds of its flesh are tightly joined;

they are firm on it, immovable.

41:24 Its heart is hard as rock,

hard as a lower millstone.

41:25 When it rises up, the mighty are terrified,

at its thrashing about they withdraw.

41:26 Whoever strikes it with a sword

will have no effect,

nor with the spear, arrow, or dart.

41:27 It regards iron as straw

and bronze as rotten wood.

41:28 Arrows do not make it flee;

slingstones become like chaff to it.

41:29 A club is counted as a piece of straw;

it laughs at the rattling of the lance.

41:30 Its underparts are the sharp points of potsherds,

it leaves its mark in the mud

like a threshing sledge.

Joel 2:8

2:8 They do not jostle one another;

each of them marches straight ahead.

They burst through the city defenses

and do not break ranks.
