Numbers 32:5-9

Wherefore, said they, if we have found grace in thy sight, let this land be given unto thy servants for a possession, and bring us not over Jordan.

And Moses said unto the children of Gad and to the children of Reuben, Shall your brethren go to war, and shall ye sit here?

And wherefore discourage ye the heart of the children of Israel from going over into the land which the LORD hath given them?

Thus did your fathers, when I sent them from Kadesh-barnea to see the land.

For when they went up unto the valley of Eshcol, and saw the land, they discouraged the heart of the children of Israel, that they should not go into the land which the LORD had given them.
