'Day' in the Bible

Then said she, Sit still, my daughter, until thou know how the matter will fall; for the man will not rest, until he have finished the thing this day.

Then said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.

And Boaz said unto the elders, and unto all the people, Ye are witnesses this day, that I have bought all that was Elimelech's, and all that was Chilion's and Mahlon's, of the hand of Naomi.

Moreover Ruth the Moabitess, the wife of Mahlon, have I purchased to be my wife, to raise up the name of the dead upon his inheritance, that the name of the dead be not cut off from among his brethren, and from the gate of his place: ye are witnesses this day.

And the women said unto Naomi, Blessed be Jehovah, who hath not left thee this day without a near kinsman; and let his name be famous in Israel.
