'Days' in the Bible

God, who in ancient days spoke to our forefathers in many distinct messages and by various methods through the Prophets,

Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;

Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared;

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.

For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:

For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:

This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;

But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions;

By faith the walls of Jericho fell down, after they were compassed about seven days.

For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness.
