The Hebrew noun omnah refers to the act of nurturing, bringing up, or fostering a child. Related to the root meaning faithfulness and firm support. It appears in Esther 2:20, describing how Esther had been nurtured by Mordecai after her parents died — a picture of faithful, covenant-keeping care.
The concept of omnah reflects God's own nurturing character. As Mordecai faithfully raised Esther, God providentially uses faithful guardians to shape His servants for His purposes. This word reminds believers that upbringing, mentorship, and formation are acts of covenant love.
