So the woman left her water pot, and went away into the city, and said to the people,
      (3.) That it was easy work, and work that was half done to their hands by those that were gone before them: One soweth, and another reapeth,John 4:37; John 4:38. This sometimes denotes a grievous judgment upon him that sows, Micah 6:15; Deuteronomy 28:30, Thou shalt sow, and another shall reap; as Deuteronomy 6:11, Houses full of all good things, which thou filledst not. So here. Moses, and the prophets, and John Baptist, had paved the way to the gospel, had sown the good seed which the New-Testament ministers did in effect but gather the fruit of. I send you to reap that whereon you bestowed, in comparison, no labour.Isaiah 40:3-5. [1.] This intimates two things concerning the Old-Testament ministry:--First, That it was very much short of the New-Testament ministry. Moses and the prophets sowed, but they could not be said to reap, so little did they see of the fruit of their labours. Their writings have done much more good since they left us than ever their preaching did. Secondly, That it was very serviceable to the New-Testament ministry, and made way for it. The writings of the prophets, which were read in the synagogues every sabbath day, raised people's expectations of the Messiah, and so prepared them to bid him welcome. Had it not been for the seed sown by the prophets, this Samaritan woman could not have said, We know that Messias cometh. The writings of the Old Testament are in some respects more useful to us than they could be to those to whom they were first written, because better understood by the accomplishment of them. See 1 Peter 1:12; Hebrews 4:2; Romans 16:25; Romans 16:26. [2.] This also intimates two things concerning the ministry of the apostles of Christ. First, That it was a fruitful ministry: they were reapers that gathered in a great harvest of souls to Jesus Christ, and did more in seven years towards the setting up of the kingdom of God among men than the prophets of the Old Testament had done in twice so many ages. Secondly, That it was much facilitated, especially among the Jews, to whom they were first sent, by the writings of the prophets. The prophets sowed in tears, crying out, We have laboured in vain; the apostles reaped in joy, saying, Thanks be to God, who always causeth us to triumph. Note, From the labours of ministers that are dead and gone much good fruit may be reaped by the people that survive them and the ministers that succeed them. John Baptist, and those that assisted him, had laboured, and the disciples of Christ entered into their labours, built upon their foundation, and reaped the fruit of what they sowed. See what reason we have to bless God for those that are gone before us, for their preaching and their writing, for what they did and suffered in their day, for we are entered into their labours; their studies and services have made our work the easier. And when the ancient and modern labourers, those that came into the vineyard at the third hour and those that came in at the eleventh, meet in the day of account, they will be so far from envying one another the honour of their respective services that both they that sowed and they that reaped shall rejoice together; and the great Lord of thee harvest shall have the glory of all.
