I know that ye will not yet fear the LORD God (Isaiah 8)

In Isaiah chapter eight, God commands Isaiah to write about his son Mahershalalhashbaz (literally "Swift is booty, speedy is prey" because prophets need to give their kids weird names). I assume the "prophetess" is Isaiah's wife, although I don't know if she's called this because she's a female prophet, or if they give such a title to prophets' wives (my guides say the latter, but if so, this is the only instance of it being used that way, which I find suspect; I'm going to believe she also had the gift of prophecy). God gives the child his name, saying that it's because before the child is old enough to speak, Judah's riches will be plundered by the king of Assyria, which God proceeds to compare to a flooding river. In verse nine, God tells the people that they will be "broken in pieces", which the SAB calls unjust, and it's a matter of opinion, but the SAB misunderstands the meaning of the verse, I think; God is not saying he will break the people of Judah for doing these things, he is saying that even if they try and form an army ("associate yourselves") or take up weapons ("gird yourselves"), the Assyrians will defeat them. (Or it possibly could be a warning to other people who want to defeat Judah that they will lose, since verse ten says "God is with us"? Actually, I'm leaning towards this, mostly because of "...give ear, all ye of far countries..." In either case, it's not a punishment for associating and girding.) Isaiah says that God told him not to be like the other people (unfaithful Judahites, or foreigners? Still not 100% sure about this.) and not to listen to conspiracy theories, but rather fear the Lord. I addressed the question of whether one should fear God at length in Joshua chapter four, where the answer was yes, but the key takeaway was why one should fear God and what it looks like. Isaiah says God is a sanctuary to those who are faithful, but in Israel and Judah, God will be a stumbling block and a snare for the unfaithful. There is prophesied a time coming when instead of seeking God, people will seek witches and wizards and communication with the dead. They should consult God's word, but they won't, so they will curse God and be cast into darkness.
