Genesis 41:34
Let him appoint officers - pekidim , visitors, overseers: translated by Ainsworth, bishops; see Genesis 39:1.
Take up the fifth part of the land - What is still called the meery, or that part of the produce which is claimed by the king by way of tax. It is probable that in Joseph' s time it was not so much as a fifth part, most likely a tenth: but as this was an extraordinary occasion, and the earth brought forth by handfuls, Genesis 41:47, the king would be justified in requiring a fifth; and from the great abundance, the people could pay this increased tax without feeling it to be oppressive.
