'Day' in the Bible

don't harden your hearts, as in the rebellion, like as in the day of the trial in the wilderness,

but exhort one another day by day, so long as it is called "today;" lest any one of you be hardened by the deceitfulness of sin.

For he has said this somewhere about the seventh day, "God rested on the seventh day from all his works;"

he again defines a certain day, today, saying through David so long a time afterward (just as has been said), "Today if you will hear his voice, don't harden your hearts."

For if Joshua had given them rest, he would not have spoken afterward of another day.

not according to the covenant that I made with their fathers, in the day that I took them by the hand to lead them out of the land of Egypt; for they didn't continue in my covenant, and I disregarded them," says the Lord.

Every priest indeed stands day by day serving and often offering the same sacrifices, which can never take away sins,

not forsaking our own assembling together, as the custom of some is, but exhorting one another; and so much the more, as you see the Day approaching.
