'On that Day' in the Bible

And David feareth God on that day, saying, 'How do I bring in unto me the ark of God?'

On that day then hath David given at the beginning to give thanks to Jehovah by the hand of Asaph and his brethren: --

And they eat and drink before Jehovah on that day with great joy, and cause Solomon son of David to reign a second time, and anoint him before Jehovah for leader, and Zadok for priest.
