Easton's 1897 Bible Dictionary:

Churl
   in Isa. 32:5 (R.V. marg., "crafty"), means a deceiver. In 1 Sam.
   25:3, the word churlish denotes a man that is coarse and
   ill-natured, or, as the word literally means, "hard." The same
   Greek word as used by the LXX. here is found in Matt. 25:24, and
   there is rendered "hard."
