What does Gabriel mean?
Gabriel is from the Hebrew Gavriʾel, “God is my strength.” Gabriel is one of the archangels who appears in Jewish, Christian and Islamic tradition.
What does Caleb mean?
Meaning genuinely contested. Traditionally derived from keleb, 'dog' (connoting a humble, devoted servant). Others split it as kol + lev, 'whole heart,' giving 'wholehearted' — a reading that suits the loyal spy of Numbers 13-14. Because the name shares the consonants k-l-b with 'dog,' that older reading cannot be cleanly ruled out; treat both as open.
