The Hebrew proper name Abiykhayil (אֲבִיהַיִל) means "My Father is strength" or "Father of might" — from ab (father) and khayil (strength, valor, army). The name appears for both men and women in the Old Testament: a Levite (Numbers 3:35), a wife of Abishur (1 Chronicles 2:29), a Gadite (1 Chronicles 5:14), a relative of Esther (Esther 2:15), and more.
The name Abihail — "My Father is strength" — belongs to a cluster of Hebrew names that confess God's power as the foundation of identity (Uzziah = "The LORD is my strength"; El-gibbar = "God is mighty"). In naming children this way, Israelite families made a daily declaration that their security and valor came from God, not from human capacity. This is the spirit of Psalm 18:1-2: "I love you, LORD, my strength..." and Philippians 4:13: "I can do all things through Christ who strengthens me." The name Abihail, borne by multiple people across generations, testifies to the enduring conviction: God is our strength.
