'Concerning' in the Bible

Then the children of Judah drew near to Joshua in Gilgal. Caleb the son of Jephunneh the Kenizzite said to him, "You know the thing that Yahweh spoke to Moses the man of God concerning me and concerning you in Kadesh Barnea.

"Behold, today I am going the way of all the earth. You know in all your hearts and in all your souls that not one thing has failed of all the good things which Yahweh your God spoke concerning you. All have happened to you. Not one thing has failed of it.
