[16]And on the following night, on the twenty-second day of this month, Jacob resolved to build that place, and to surround the court with a wall, and to sanctify it and make it holy for ever, for himself and his children after him.
[17]And the Lord appeared to him by night and blessed him and said unto him: 'Thy name shall not be called Jacob, but Israel shall they name thy name.'
[27]And he celebrated there yet another day, and he sacrificed thereon according to all that he sacrificed on the former days, and called its name 'Addition,' for this day was added and the former days he called 'The Feast '.
[28]And thus it was manifested that it should be, and it is written on the heavenly tablets: wherefore it was revealed to him that he should celebrate it, and add it to the seven days of the feast.
[29]And its name was called 'Addition,' because that it was recorded amongst the days of the feast days, according to the number of the days of the year.
