Albert Barnes Commentary Joshua 14:6

"Then the children of Judah drew nigh unto Joshua in Gilgal: and Caleb the son of Jephunneh the Kenizzite said unto him, Thou knowest the thing that Jehovah spake unto Moses the man of God concerning me and concerning thee in Kadesh-barnea." — Joshua 14:6 (ASV)

The children of Judah - No doubt, in particular, the kinsmen of Caleb, and perhaps other leading men of the tribe. These came before Joshua, with Caleb, in order to make it clear that they supported his claim, to be secured in the possessions promised him by Moses before the general allotment was to be made to the tribes (compare the marginal references).
