'Days' in the Bible

has in these last days spoken [with finality] to us in [the person of One who is by His character and nature] His Son [namely Jesus], whom He appointed heir and lawful owner of all things, through whom also He created the universe [that is, the universe as a space-time-matter continuum].

In the days of His earthly life, Jesus offered up both [specific] petitions and [urgent] supplications [for that which He needed] with fervent crying and tears to the One who was [always] able to save Him from death, and He was heard because of His reverent submission toward God [His sinlessness and His unfailing determination to do the Father’s will].

Without [any record of] father or mother, nor ancestral line, without [any record of] beginning of days (birth) nor ending of life (death), but having been made like the Son of God, he remains a priest without interruption and without successor.

However, God finds fault with them [showing its inadequacy] when He says,“Behold, the days will come, says the Lord,When I will make and ratify a new covenantWith the house of Israel and with the house of Judah;

“For this is the covenant that I will make with the house of IsraelAfter those days, says the Lord:I will imprint My laws upon their minds [even upon their innermost thoughts and understanding],And engrave them upon their hearts [effecting their regeneration].And I will be their God,And they shall be My people.

“This is the covenant that I will make with themAfter those days, says the Lord:I will imprint My laws upon their heart,And on their mind I will inscribe them [producing an inward change],”He then says,

But remember the earlier days, when, after being [spiritually] enlightened, you [patiently] endured a great conflict of sufferings,

By faith the walls of Jericho fell down after they had been encircled for seven days [by Joshua and the sons of Israel].
