In Leviticus 6:16, 'Aaron and his sons eating the remainder' signifies a person's reciprocation and making something one's own. This represents conjunction by means of love and charity. This is why they were commanded to eat it 'in a holy place.'

5. “Day” or “time” in these passages mean the Lord’s advent.

A day of gloom, of darkness, of haziness, one without light, one of devastation, of the final iniquity, or of destruction, means the Lord’s advent when He was no longer known and when as a consequence nothing any longer of the church remained.

A cruel day, a dreadful day, a day of wrath, of anger, of tumult, of visitation, of sacrifice, of retribution, of distress, of war, or of a cry, means the Lord’s coming to judge.

A day when Jehovah alone will be exalted; when He shall be one and His name one; when an offshoot of Jehovah shall be beautiful and glorious; when the righteous shall flourish; when Jehovah shall vivify; when He will seek His flock; when He will make a new covenant; when the mountains drip new wine; when living waters flow from Jerusalem; when people will look to the God of Israel; and the like — these mean the Lord’s advent to establish a new church, one that will acknowledge Him as the redeemer and savior.
