A — 1: νουθεσία
(Strong's #3559 — Noun Feminine — nouthesia — noo-thes-ee'-ah )

lit., "a putting in mind" (nous, "mind," tithemi, "to put"), is used in 1—Corinthians 10:11 , of the purpose of the Scriptures; in Ephesians 6:4 , of that which is ministered by the Lord; and in Titus 3:10 , of that which is to be administered for the correction of one who creates trouble in the church. Nouthesia is "the training by word," whether of encouragement, or, if necessary, by reproof or remonstrance. In contrast to this, the synonymous word paideia stresses training by act, though both words are used in each respect.
