What is the origin of the phrase – Ladies first?

According to Judaism and the Torah, the ‘ladies first’ rule is a very old tradition. The story goes that when Moses was instructed to inform the people of Israel about the Torah, he was told to “speak to the house of Jacob, and tell the sons of Israel.” Since the house of Jacob appears first in the instructions, and it refers to women, the theory follows that Moses had to speak first with the ladies. Probably this is the origin of the phrase ‘ladies first’.
