The 10 plagues against Mitsraim (Egypt) were judgments against the false deities of the land, to show the descendants of Yisra’el (Israel) and the people of the land Who was the true God.
Moshe (Moses) in Exodus 6 said his lips were “uncircumcised” and insisted that prevented him from sharing The Name of God to Yisra’el (Israel). We know about circumcision of a man’s privates and metaphorically of the “heart,” but what is this, and how is it connected to sharing knowledge of The Name?
The account of Moshe (Moses) encountering God via the burning bush has spawned a number of interpretations and explanations about who Moshe encountered, how the bush could be burning yet not consumed, etc. Yet the declaration of the Name of God there and the signs God gave Moshe to show the leaders of Yisra’el is the important element. The Name and the signs would strengthen not only Moshe but the leadership for something powerful God would do on Earth via Yisra’el in the mighty empire of Mitsraim (Egypt).
This study also explores the seeming strange vignette of God on the warpath against Moshe’s family, placated only by Tzipporah’s circumcising the son. This appears to be a foreshadowing of the 10th plague against Mitsraim.
