All the nations of the earth shall be blessed in him (Isaiah 49)

Isaiah chapter 49 doesn't have a lot of notes, but let's see what's there. Mostly, there's a lot of verses marked absurd, and as is often the case, it's not really clear to me what's supposed to be absurd about them. The first two verses are marked, and it may be because Isaiah speaks to "islands", but as I said previously when this happened, this just means Isaiah is addressing the inhabitants of island nations. Verse two talks about Isaiah's mouth being like a sword; this sort of imagery is used throughout the Bible as a way of saying that in their own way, words can cut. In verse 16, God says he has engraved Israel on the palm of his hand, and I suppose this sounds absurd, but seeing as God doesn't have physical hands, I believe it's a figure of speech to say that God is always looking out for Israel, and keeps them in his mind constantly. Verse 23 talks about kings being "nursing fathers" which is definitely odd imagery, but I think the point is that Israel is going to be provided for. This verse also talks about kings and queens licking dust off of Israel's feet, which I assume is just saying that even the leaders of foreign nations will be humbled before Israel.

Going back to verse six, God says that even the Gentiles will be blessed through Israel because God will give them a "light" for salvation to all the earth. Of course, a Christian is going to assume that the "light" is Jesus, but whatever it is, this is a recurring theme going back to Abraham, that the descendants of Abraham will bring a blessing to the world. Verse seven talks about "the Holy One of Israel", who is going to be rejected by the nation, but people will worship him, once again very Jesus-like imagery. The name "Sinim" in verse twelve appears nowhere else, so nobody knows what it refers to. In verse 14, Israel says that God has forsaken them, but the next few verses assure that this could never happen (including the verse about Israel being engraved on God's palm).

The final verse is marked for harsh language, injustice, and intolerance. It is pretty harsh, but this is talking about nations that oppress Israel, so there's an understanding that they are evil.
