'Beginning' in the Bible

And, Thou, Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands:

For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;

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