what does that have to do with your other behaviour?

This is related. It looks like King James got this one wrong too.

Isaiah 3:12 King James Version (KJV)
12 As for my people, children are their oppressors, and women rule over them. O my people, they which lead thee cause thee to err, and destroy the way of thy paths.

They may have copied it from Geneva.

Isaiah 3:12 1599 Geneva Bible (GNV)
12 [a]Children are extortioners of my people, and women have rule over them: O my people, they that lead thee, cause thee to err, and destroy the way of thy paths.

Footnotes:
Isaiah 3:12 Because the wicked people were more addicted to their princes, than to the commandments of God, he showeth that he would give them such princes, by whom they should have no help, but that should be manifest tokens of his wrath, because they should be fools and effeminate.

Here is my post:
In the Septuagint that verse does not mention children or women. It appears to have been changed to keep women suppressed.

The Septuagint was translated from Hebrew to Greek centuries before the Masoretes added their system of vowel points to the Hebrew text. The Septuagint’s version of Isaiah 3:12a (translated into English) reads: “O my people, your extractors strip you, and extortioners rule over you.” https://www.curezone.org/forums/fm.asp?i=2397838#i

"Whatever the original word may have been, it is clear that God was saying that Judah would be led, or bullied, by incompetent leaders."
