New Defender's Study Bible Notes
20:2 agreed. Note that this first group of workers wanted a definite contract with the householder before they would work. The later groups were willing to work simply by faith in the employer’s word that “whatsoever is right I will give you” (Matthew 20:4), and He rewarded their faith abundantly. Even those hired at the eleventh hour received the same wages, for they would have been willing to work all day (Matthew 20:7) if they had known. Thus, rewards for Christian service are based more on motive and opportunity than on quantity. See also I Corinthians 3:13-15.
