Miciah is an uncommon given name of Hebrew origin, meaning "Who is like God?". It is derived from the question asked by the prophet Micah in the Bible (Micah 7:18), expressing awe and admiration for God's mercy and forgiveness. The name Miciah is often associated with its variant spellings, such as Micaiah and Mikayla, which can be used for both boys and girls due to their popularity as unisex names. In the Bible, Micaiah is also the name of a prophet who served during the reigns of Kings Ahab and Jehoshaphat in ancient Israel.
"The name Miciah has had a fluctuating popularity over time, with peaks in the late 90s and early 2000s, but it has generally been quite uncommon, with fewer than 20 births per year in most years since 1991."
