'Instructing' in the Bible

On one of the days, as Jesus was instructing the people in the temple [area] and preaching the good news (gospel), the chief priests and the scribes along with the elders confronted Him,

Some men came down from Judea and began teaching the brothers, “Unless you are circumcised in accordance with the custom of Moses, you cannot be saved.”

We proclaim Him, warning and instructing everyone in all wisdom [that is, with comprehensive insight into the word and purposes of God], so that we may present every person complete in Christ [mature, fully trained, and perfect in Him—the Anointed].
