• Isaiah

I remember reading somewhere that Hebrew poetry uses repetition a lot, instead of rhyme (and maybe meter). In Isaiah 2, this is really evident. The helpful part of this is that if you don't understand a phrase or sentence, the prophet always repeats himself, so you have a pair of analogies to use as similar sayings. They are often finished by testimony or admonition.

• the mountain of the Lord / the house of the God of Jacob
• he will teach of us his ways / we will walk in his paths

• he shall judge among the nations / shall rebuke many people
• they shall beat their swords into plowshares/ their spears into pruning hooks

An invitation

• come ye / let us walk

His style is also helpful with confusing verses:

• 2:7 - horses / chariots
• 2:9 - the mean man / the great man
• 2:10 - the rock / the dust
• 2:11 - the lofty looks / the haughtiness
• 2:12 - proud and lofty / lifted up
• 2:13 - the cedars of Lebanon / high and lifted up / the oaks of Bashan
• 2:15 - high towers / fenced walls
• 2:19 - the holes of the rocks / the caves of the earth
• 2:20 - the moles / the bats
• 2:21 - the clefts of the rocks / the tops of the ragged rocks
