Anaqah (אֲנָקָה, H604) is a homograph of H603 but refers to a different thing — a small lizard, most likely the gecko, named possibly for the sound it makes. It appears in Leviticus 11:30 in the list of swarming creatures that are unclean. Ancient rabbis and modern scholars generally identify it as a type of gecko.
The Levitical purity laws regarding swarming creatures like the anaqah (gecko) taught Israel a fundamental principle: holiness means separation from what is defiling. While seemingly mundane, touching such creatures caused ritual uncleanness (Leviticus 11:31). The New Testament interprets these laws through Christ who cleanses us from all defilement (1 John 1:7), yet the principle remains — "Let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God" (2 Corinthians 7:1).
