'Three day' in the Bible

Then he separated them from Jacob by a three-day journey, while Jacob was taking care of the rest of Laban's flocks.

And they said, "The God of the Hebrews has met with us. Let us go a three-day journey into the desert so that we may sacrifice to the Lord our God, so that he does not strike us with plague or the sword."

We must go on a three-day journey into the desert and sacrifice to the Lord our God, just as he is telling us."
