When the groom’s father said that the bridal chamber was finished the groom would gather his friends and go to the bride’s home in the middle of the night to steal her away. Because the bride did not know the day or the hour that this would happen; from the day of her betrothal, she had to be ready for this to happen
at any time. She and her attendants would sleep at her house in their wedding attire.
Because there were no street lights at that time, the bride was required to keep a lamp properly trimmed at all times, because it would be she who would lead the wedding procession with great rejoicing through the darkened streets to the home the groom had prepared for her. Y'shua alluded to this tradition when he told this parable:
"At that time the kingdom of heaven will be like ten virgins who took their lamps and went out to meet the bridegroom. Five of them were foolish and five were wise. The foolish ones took their lamps but did not take any oil with them. The wise, however, took oil in jars along with their lamps. The bridegroom was a long time in coming, and they all became drowsy and fell asleep. At midnight the cry rang out: 'Here's the bridegroom! Come out to meet him!' Then all the virgins woke up and trimmed their lamps. The foolish ones said to the wise, 'Give us some of your oil; our lamps are going out.' 'No,' they replied, there may not be enough for both us and you. Instead, go to those who sell oil and buy some for yourselves.' But while they were on their way to buy the oil, the bridegroom arrived. The virgins who were ready went in with him to the wedding banquet. And the door was shut. Later the others also came. 'Sir! Sir!' they said. 'Open the door for us!' But he replied, 'I tell you the truth, I don't know you.' Therefore keep watch, because you do not know the day or the hour.”(Matthew 25:1-13 NIV)
The oil in this story represents the Holy Spirit, and Y'shua is warning us that we need to be filled with the Spirit of God when he returns for His bride so that we will not be left behind.
The stealing away of the bride is also what is alluded to in 1 Thessalonians 4:16-17 which reads: "For the Lord Himself will descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first. Then we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air, and so we shall always be with the Lord. (NASB)
Is your lamp full of the oil of the Holy Spirit? Are you listening for the shout of the the archangel and the Shofar of Yahveh? More on the wedding tradition of Y'shua
