'Beginning' in the Bible

And, "You, Lord, laid the foundation of the earth in the beginning, and the heavens are the works of your hands;

how will we escape [if we] neglect so great a salvation which had [its] beginning [when it] was spoken through the Lord [and] was confirmed to us by those who heard,

For we have become partners of Christ, if indeed we hold fast the beginning of [our] commitment steadfast until the end,

For indeed, [although you] ought to be teachers {by this time}, you have need of someone to teach you again the beginning elements of the oracles of God, and {you have need of} milk, not solid food.

without father, without mother, without genealogy, having neither beginning of days nor end of life, but resembling the Son of God--he remains a priest for all time.
