“And it came to pass on the morrow, which was the second day of the month, that David's place was empty: and Saul said unto Jonathan his son, Wherefore cometh not the son of Jesse to meat, neither yesterday, nor to day?”
King James Version (KJV)
20:27 Son of Jesse - So he calls him in scorn, to note the meanness of his original; and as not deigning to call him by his proper name. To day - For the uncleanness which came by some chance, usually lasted but for one day.
