If a man suspects his wife of unfaithfulness, he can go to the priest and undergo a ritual test of adultery. She takes an oath that she is innocent unless the dirty water she drinks makes her sick. The priest writes out the oath and scrapes the ink into the water for her to drink, too. This provides a way to resolve a lingering suspicion in a marriage, kind of like God gave the Urim and Thummim to consult to know His will. Given for a time, for Israel.
You could take a Nazirite vow, of special devotion to the Lord. You don't eat or drink anything from the vine or grape, and don't cut your hair. At the end of the period of time, you bring an offering to the tabernacle, cut your hair and offer that, too. Then you may drink wine again.
God gives Aaron a blessing to give Israel: three-fold blessing of Yahweh to keep them in grace and peace.
How this is about Jesus
- Jesus need never use this with His bride, the Church, as He is omniscient. He has no undue suspicions or jealousies, but rather knows our every fault and weakness. He loves and accepts us rather than accusing us, in spite of this knowledge.
- He was set apart to serve God at His baptism, when the Holy Spirit rested on Him.
- Jesus IS God's blessing: God's face shone upon us (2 Corinthians 4:6).
Sins this reveals
- When we sin, we figure a quick apology will do, rather than consider how to make it up completely to the person we have offended.
- We try to hide sin from others; we suspect others of sin when they've done nothing wrong.
- Samson broke all the Nazirite vow rules, which God put him under (Judges 13:4-5). God still used him when he sought God.
