Luke 3:14

And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse any falsely; and be content with your wages.

The preaching of John did not remain without its effect upon the people. Some there were that were struck in their hearts, and who now became perplexed penitents. They accepted the rebuke of John in all meekness, they acknowledged their sins, but they were at a loss as to the manner in which they should now give evidence of their change of heart; they needed lessons in sanctification. And so John makes the application of the Law in their individual cases. The great fault of the people in general was their grasping meanness. If they had merely discouraged promiscuous begging due to laziness, they would have acted laudably. But they were mercenary and grasping, and therefore John teaches them that they should be willing to share with the needy, Isaiah 58:3; Daniel 4:24. To help the poor with clothing and food is not only well-pleasing to God, but under circumstances may become a matter of duty demanded by the worship of Him. Matthew 10:42. The publicans also felt the justice of John's general rebuke and submitted the question as they came to be baptized: Teacher, what shall we do? Their sin was covetousness, greed and therefore overreaching and fraud. To them he gave instructions not to exact payment in excess of the fixed duty. This was a comparatively easy matter for them, since the system permitted graft on a wholesale scale, and it was nothing unusual for a publican to amass a fortune. This they could not continue if their repentance was sincere; a hint to the grafters of our day, not to mention, food profiteers and other pirates that ply their trade under the guise of legitimate business. The last class whom John gave special instructions were soldiers, probably such as mixed with the people out of curiosity or were sent down by the authorities in anticipation of trouble. Upon their question as to their proper behavior under the circumstances, John gives them instructions to extort neither by force nor by fraud, by misrepresentation, and to be satisfied with their wages. In the work of their calling, the temptation to bully the people, and to receive bribes and hush-money, was very great, Matthew 28:12. They extorted money by intimidation in the case of the poor, they obtained money by acting as informers against the rich. John's words were a lesson for each one to consider his own station according to the Law of God.
