Génesis 50

And forty days were fulfilled for him; for so are fulfilled the days of those which are embalmed: and the Egyptians mourned for him threescore and ten days.

Y cumpliéronle cuarenta días, porque así cumplían los días de los embalsamados, y lloráronlo los Egipcios setenta días.

Forty days were used for him, for that is how many days it takes to embalm. The Egyptians wept for Israel for seventy days.
