'Wholly' in the Bible

You shall give the Levites to Aaron and to his sons [as servants and helpers]; they are to be given wholly to him from among the Israelites.

and they shall put on it a covering of porpoise skin (fine leather), and shall spread over that a cloth of pure blue, and shall insert the carrying poles of the ark.

for they are wholly given to Me from among the Israelites. I have taken them for Myself instead of all who are born first, the firstborn of all the Israelites.

‘None of the men who came up from Egypt, from twenty years old and upward, shall see the land which I promised to Abraham, to Isaac, and to Jacob, because they have not followed Me completely,

except Caleb the son of Jephunneh the Kenizzite and Joshua the son of Nun, for they have followed the Lord completely.’
