...or was it a goat?

Passover is predicated on the well known story that the Hebrews were required to slaughter a lamb and spread the blood on their door to inform Yahweh that they should not suffer the curse whereby all firstborn will be cruelly put to a senseless death.

If we consider that this is meant as a dramatic fictional story, then it renders the entire Bible moot as the story is the antecedent for every event that transpires later - including the engraving of the 10 commandments and the Cruxifiction. So this must be an accurate story, not a parable, or the Bible itself is moot.

For believers then the mark was either real and meaningless or real and meaningful . If it was real and meaningless, then either Moses or Yahweh presented inaccurate information, misrepresented it as vital once again rendering the Bible moot. If Yahweh or moses could lie or make such a serious and sadistic mistake, there is no reason to believe anything they record.

For believers then the mark must have been real and meaningful. If the mark was meant as a test for the Hebrews, but Yahweh would not slaughter the first born even if they neglected to place the mark or didn't place it properly, then Yahweh is a cruel prankster who cannot be trusted, once again rendering the Bible moot.

For believers then the mark must have been real, meaningful, and carried the consequence of death. If Yahweh required the mark to identify his own followers, then he is blind. If Yahweh would murder his own followers for such an innocent mistake, then he is a sadist.
