¹ go to those who sell oil and buy some for yourselves. Note! buy and sell oil — think spiritual equivalent: the truth or the Holy Spirit. The Holy Spirit has been referred to as talents in the parable of the talents. The Holy Spirit has been referred to as gold, white garments, and eye salve in Rev 3:18: "I counsel you to buy from me gold refined and tried in the fire, so that you may be rich; and white garments, so that you may be clothed and the shame of your nakedness may not appear; and anoint your eyes with eye salve, so that you may see." Look at the words buy and sell spiritually: "Buy the truth, and do not sell it; also wisdom, and discipline, and understanding." Pro 23:23. Obviously you cannot buy the truth, it is a metaphor for acquire the truth, and sell is a metaphor for letting your teachings from Christ's spirit go cold by disobedience; teachings that you hear are are spirit and life-giving, (the life of God): The words that I speak to you are spirit, and they are life-giving. John 6:63. So, what is the life of God? Jesus told us: I am the way, the truth, and the life, John 14:6; and I am the light of the world. He who follows me shall not walk in darkness, but shall have the Light of Life. John 8:12. Isaiah further shows how buying is a metaphor for acquiring more of the Holy Spirit by listening:

Come, everyone who thirsts, come to the waters, and he who has no money, come, buy and eat; yes, come, buy wine and milk without money and without price. Why do you spend money for that which is not bread? And your hard-earned money for that which does not satisfy? Listen diligently to me, and eat that which is good, and let your soul delight itself in abundance. Incline your ear, and come to me. Hear [and obey], and your soul shall live. Isa 55:1-3

The wise virgins told the foolish virgins to go and obtain more truth, more life, more light, more Holy Spirit using the metaphor of buying and selling oil.

This (the Holy Spirit) is what those without the mark of the beast were unable to buy or sell; they were unable to seek the Holy Spirit, (buy and sell), in any way except through the Roman sect; and those who differed, so without the mark of the beast, were killed if they did not attend Catholic masses and take the Eucharist at least every 90 days. Nine million souls were put to death in the Inquisition by the Roman Catholic sect in 800 to 1500 AD. See the Footnote to Revelation 13:16-17, for additional explanation.
