an'-k'-l (in older editions of the King James Version, ancle):
From Hebrew me'aphecayim literally, "water of ankles," i.e. shallow water (Ezekiel 47:3); "anklebones" (Acts 3:7) from sphudron "ankle chains" (the King James Version "chains"), from a Hebrew root meaning "to walk about proudly" (Numbers 31:50). The same Hebrew word is translated "bracelet" (2 Samuel 1:10), but in Isaiah 3:20 another word from the same root "ankle chains" (the King James Version "ornaments of the legs"). Compare ANKLET (Isaiah 3:18).
