I know when you were little girls
You dreamt of being in my world
Don’t forget it, don’t forget it
Respect that, bow down bitches

This seems to be directed towards Keri Hilson who took shots at Beyoncé in “Turning Me On (Remix)” a long time ago.

Your vision cloudy if she think that she the best
You can dance you can sing, but you need to move it ‘to the left’
She need to go have some babies, she need to sit down she fake
Go head tell these folks how long I’ve been writing your songs
I been putting you on just check your credits hoe

She could also very well be talking about Rihanna too:

Since the reinterpretation of “Bow Down” as “***Flawless” on her 2013 self-titled album, Bey has described the genesis of the track (and the “bow down” lyric):

“The reason I put out Bow Down is because I woke up, I went into the studio, I had a chant in my head, it was aggressive, it was angry, it wasn’t the Beyoncé that wakes up every morning. It was the Beyoncé that was angry. It was the Beyoncé that felt the need to defend herself. … People like it? Great, they don’t? they don’t. … But I feel strong, and anyone who says it’s disrespectful — just imagine the person that hates you, just imagine the person that doesn’t believe in you, and look in the mirror and say, “Bow down, bitch!“ And I guarantee you’ll feel gangsta.”
