'Persons' in the Bible

All the descendants of Jacob were seventy people; Joseph was [already] in Egypt.

Now if the household is too small for a lamb [to be consumed], let him and his next door neighbor take one according to the number of people [in the households]; according to what each man can eat, you are to divide the lamb.

This is what the Lord has commanded: ‘Let every man gather as much of it as he needs. Take an omer for each person, according to the number of people each of you has in his tent.’”
