John Gill Commentary 2 Samuel 12:2

"The rich man had exceeding many flocks and herds;" — 2 Samuel 12:2 (ASV)

The rich [man] had exceeding many flocks and herds . ] In which the wealth of men lay in those times and countries; these in the parable signify David's wives and concubines, which were many; he had six wives in Hebron, and he took more wives and concubines out of Jerusalem, when he was come from Hebron, (2 Samuel 3:2–5) (5:13) ; and besides his master's, or Saul's wives, given to him, (2 Samuel 12:8) .
