'Familiar' in the Bible

He said to them, “Therefore every scribe who has become a disciple of the kingdom of heaven is like the head of a household, who brings out of his treasure things that are new and fresh and things that are old and familiar.”

I am speaking in [familiar] human terms because of your natural limitations [your spiritual immaturity]. For just as you presented your bodily members as slaves to impurity and to [moral] lawlessness, leading to further lawlessness, so now offer your members [your abilities, your talents] as slaves to righteousness, leading to sanctification [that is, being set apart for God’s purpose].
