It is used two different ways. One is the call to murder Jews, the other is a solo effort to be closer to god. I only know this because it is in the UK media of late. The sad part people are using on the pro-Palestinians marches knowing full well it will insight a violent reaction.
EDIT: others are throwing in different meanings in this post. It seems it has many variations. Not being Jewish or Muslim shows I do not have enough of a vested interest to understand all of the context surrounding this.
One of my kids came out as gay. I grew up in a very homophobic environment in the 70s. I would quite often called timid people puffs etc. Sometimes around my kids, because that was how I grew up. You discouraged timid behaviour to stop them getting bullied. Realising one of your kids is gay was a real eye opener for me as to how bad these phrases are.
I would never treat a gay person differently. I just saw it as an expression that was common when I was young, and also in the environment I worked in. For context, I used to play squash with a guy from work, who everyone was convinced was gay. He actually got married in a heterosexual relationship a few years later, but whether he was or wasn’t never bothered me. This ofc doesn’t excuse the practise, it just shows how warped I was.
