“Gebirah” is the word for the Queen who is the Mother of the King. It’s a good word to Google.
Suppose Solomon had 400 wives and 300 concubines… who would he choose to be his queen? So many unions were political in nature… who was it okay to offend by not-choosing? Isn’t it a whole lot more straightforward (and theoretically/relatively safe) to align yourself with your mother (who is presumably most loyal to her son)? How often does the king owe his throne to his mother’s efforts to place him there? And wouldn’t she have a whole lot of experience, from years of dwelling in that kind of politically-charged environment, that would give her the qualities needed to be a trusted advisor.
So, the same thing is true for Mary. She was given the graces she needed to be the Mother of God. If you’ve been prepared to be Mother of God, can you think of anyone more qualified to be Queen of the Universe, if Jesus is King?

Brant Pitre’s book a read, which came out last year. It has a lot of awesome things to unpack.
