Why do so many YouTube prophets & prophetesses claim that the LORD now uses terms that he didn’t in the scriptures?

Unless I missed it, I couldn’t find the LORD using the direct term, “My children”, when speaking to his people.

He speaks of his children using that expression, for example in Jeremiah 10:20.

However he doesn’t call his people, “My children”, when directly speaking to them.

            Also, the LORD doesn’t use the term, “My daughter” when speaking to someone.

In Isaiah 43:6 the LORD is only speaking about his daughters, “bring my sons from far, and my daughters from the ends of the earth”.

Jephthah uses the term, “My daughter” in Judges 11:35.

Naomi uses, “My daughters” 3 times, “My daughter” 5 times, and Boaz uses, “My daughter” 3 times.

However the LORD does not speak directly using the term, “My daughter”, anywhere that I could find.

            Now, YouTube prophets & prophetesses, claim that the LORD said, “My children” or “My daughter” to them.

Is it expected to believe them, that they are speaking from the LORD, or even for the LORD, when they say that?

Yet they don’t seem to speak like he does:

 

John 10:2 But he that entereth in by the door is the shepherd of the sheep.

3 To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out.

4 And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice.

5 And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.

 

Wouldn't some say that I'm sort of blaspheming the Holy Ghost by even thinking something like this?
