At the age of five, children began to learn the arts and duties of life under the care of their fathers (Deuteronomy 6:20-25; 11:19).
To have a numerous family was regarded as a mark of divine favor (Genesis 11:30; 30:1; 1 Samuel 2:5; 2 Samuel 6:23; Psalms 127:3; 128:3).
Figuratively, the name is used for those who are ignorant or narrow-minded (Matthew 11:16; Luke 7:32; 1 Corinthians 13:11).

Believers are “children of light” (Luke 16:8; 1 Thess. 5:5) and “children of obedience” (1 Peter 1:14).
