'Guardians' in the Bible

And the one who was in charge of the household, and the one who was overseer of the city, the elders, and the guardians [of the children] sent word to Jehu, saying, “We are your servants and we will do whatever you tell us, but we will not make any man king; do what is good in your eyes.”

“Kings will be your attendants,And their princesses your nurses.They will bow down to you with their faces to the earthAnd lick the dust of your feet;And you shall know [with an understanding based on personal experience] that I am the Lord;For they shall not be put to shame who wait and hope expectantly for Me.

Take care and be on guard for yourselves and for the whole flock over which the Holy Spirit has appointed you as overseers, to shepherd (tend, feed, guide) the church of God which He bought with His own blood.

but he is under [the authority of] guardians and household administrators or managers until the date set by his father [when he is of legal age].
