Genesis 1:23; Genesis 30:17; Genesis 47:24 (King James Version)

23 And the evening and the morning were the fifth day. 17 And God hearkened unto Leah, and she conceived , and bare Jacob the fifth son. 24 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.
