Read Genesis 47:24 Using Other Translations
And it shall come to pass in the increase, that ye shall give the fifth part unto Pharaoh, and four parts shall be your own, for seed of the field, and for your food, and for them of your households, and for food for your little ones.
And at the harvests you shall give a fifth to Pharaoh, and four fifths shall be your own, as seed for the field and as food for yourselves and your households, and as food for your little ones."
Then when you harvest it, one-fifth of your crop will belong to Pharaoh. You may keep the remaining four-fifths as seed for your fields and as food for you, your households, and your little ones.”
