'Age' in the Bible

above every principality, and authority, and power, and dominion, and every name named, not only in this age, but also in that to come;

in which ye once walked according to the age of this world, according to the ruler of the authority of the air, the spirit who now works in the sons of disobedience:

to him be glory in the assembly in Christ Jesus unto all generations of the age of ages. Amen).
