'First Day' in the Bible

The first day of unleavened bread, the disciples came to Jesus saying unto him, "Where wilt thou that we prepare for thee to eat the paschal lamb?"

And the first day of sweet bread, when men offer the paschal lamb, his disciples said unto him, "Where wilt thou that we go and prepare that thou mayest eat the Easter lamb?"

And when they were come to him, he said unto them, "Ye know from the first day that I came unto Asia, after what manner I have been with you at all seasons,

because of the fellowship which ye have in the gospel, from the first day unto now;

which is come unto you, even as it is into all the world, and is fruitful as it is among you, from the first day in the which ye heard of it, and had experience in the grace of God in the truth,
