Leviticus 5:5-6 - ”When anyone is guilty in any of these ways, he must confess in what way he has sinned and, as a penalty for the sin he has committed, he must bring to the Lord a female lamb or goat from the flock as a sin offering; and the priest shall make atonement for his sin”
Animal sacrifice was the only way to atone for sins in the Old Testament. Without the shedding of blood, there was no forgiveness (see the description in Hebrews 9:22). The book of Leviticus is entirely about priestly sacrifices, ceremonial cleanness, and other priestly duties – all of which foreshadow the work of Jesus, our Great High Priest. The various sacrifices described in Leviticus all foreshadow different aspects of Jesus’ atoning work on the cross. His atonement was multi-faceted, and we see all the facets in different Old Testament passages. This passage describes the “sin offering,” the most basic sacrifice of atonement.
Esther 8:8 - “Now write another decree in the king’s name on behalf of the Jews as seems best to you, and seal it with the king’s signet ring—for no document written in the king’s name and sealed with his ring can be revoked.“
The ancient Persians had an unusual custom in their legal system – the king’s official decrees were irrevocable or permanent. This created problems when the king wanted to undo something he had already decreed – he could not retract his edict (see Daniel 6:11-15 for another story where this problem arose). This strict Persian custom brought stability in their legal system, but sometimes produced unjust results. In the book of Esther, the only way the king can counteract his first edict is to give a second one authorizing resistance against the first edict.
Esther 7:9-10 – “Then Harbona, one of the eunuchs attending the king, said, ‘A gallows seventy-five feet [50 cubits] high stands by Haman’s house. He had it made for Mordecai, who spoke up to help the king.’ The king said, ‘Hang him on it!’ So they hanged Haman on the gallows he had prepared for Mordecai. Then the king’s fury subsided…”
Haman, the enemy of God’s people, had planned to have Mordecai killed (impaled or crucified) on a tall execution stake. The word “gallows” in the original was actually a pole or cross to which they would impale the victim. In an unexpected turn of events, Haman himself dies on the very execution stake that he planned to use to kill God’s servant.
