'Slain' in the Bible

and he saith, 'Who set thee for a head and a judge over us? to slay me art thou saying it, as thou hast slain the Egyptian?' and Moses feareth, and saith, 'Surely the thing hath been known.'

But Moses said, “It is not right [or even possible] to do that, for we will sacrifice to the Lord our God what is repulsive and unacceptable to the Egyptians [that is, animals that the Egyptians consider sacred]. If we sacrifice what is repulsive and unacceptable to the Egyptians, will they not riot and stone us?

and Mine anger hath burned, and I have slain you by the sword, and your wives have been widows, and your sons orphans.
