Numbers 32:23 Meaning and Commentary

Numbers 32:23

But if ye will not do so
As they promised they would, and Moses insisted on it that they should:

behold, ye have sinned against the Lord
making such a request, and not fulfilling the conditions on which it was granted:

and be sure your sin will find you out;
fly in their faces, accuse them in their consciences, charge and load them with guilt, and bring deserved punishment upon them: sin may be put, as it often is, for the punishment of sin, which sooner or later will find out and come upon the impenitent and unpardoned sinner.

Numbers 32:23 In-Context

23 But if you do not keep your promise, I warn you that you will be sinning against the Lord. Make no mistake about it; you will be punished for your sin.
24 So build your towns and the enclosures for your sheep, but do what you have promised!"
25 The men of Gad and Reuben said, "Sir, we will do as you command.
