perhaps from the same as ὄρος (through the idea of elevation); the sky; by extension, heaven (as the abode of God); by implication, happiness, power, eternity; specially, the Gospel (Christianity):--air, heaven(-ly), sky.
from a compound of ἐκ and a derivative of καλέω; a calling out, i.e. (concretely) a popular meeting, especially a religious congregation (Jewish synagogue, or Christian community of members on earth or saints in heaven or both):--assembly, church.
