'Beginning' in the Bible

And, Thou, Lord, in the beginning didst lay the foundation of the earth, And the heavens are the works of thy hands:

for we are become partakers of Christ, if we hold fast the beginning of our confidence firm unto the end:

without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like unto the Son of God), abideth a priest continually.
