'Day' in the Bible

For to which of the angels said he ever, Thou art my Son: this day have I begotten thee? and again, I will be to him for father, and he shall be to me for son?

harden not your hearts, as in the provocation, in the day of temptation in the wilderness;

But encourage yourselves each day, as long as it is called To-day, that none of you be hardened by the deceitfulness of sin.

For he has said somewhere of the seventh day thus, And God rested on the seventh day from all his works:

again he determines a certain day, saying, in David, 'To-day,' after so long a time; (according as it has been said before), To-day, if ye will hear his voice, harden not your hearts.

For if Jesus had brought them into rest, he would not have spoken afterwards about another day.

not according to the covenant which I made to their fathers in the day of my taking their hand to lead them out of the land of Egypt; because they did not continue in my covenant, and I did not regard them, saith the Lord.

not forsaking the assembling of ourselves together, as the custom is with some; but encouraging one another, and by so much the more as ye see the day drawing near.
