To "go before" in the Bible means either to lead or to prepare, depending on context. When it is said of the Lord or things representing the Lord -- the Ark of the Covenant, an angel, the pillars of cloud and fire -- it means to lead. When it is said of other people -- John the Baptist, for example, was to "go before the face of the Lord" -- it means to prepare people for what is to follow.

10399. 'Rise, make [us] gods to go before us' means producing falsities that figure in religious teachings and worship, thus producing things of an idolatrous nature. This is clear from the meaning of 'gods' as truths, dealt with in 4295, 4402, 7010, 7268, 7873, 8301, and in the contrary sense as falsities, 4402(end), 4544, 7873, so that 'making gods' means producing falsities that figure in religious teachings, or teachings composed of falsities; and from the meaning of 'to go before us' as falsities for them to follow, thus falsities according to which they may establish their worship. The fact that 'making gods to go before us' means producing things of an idolatrous nature is self-evident. Idolatry furthermore consists in worshipping external things devoid of internal ones, see 4825, 9424. But something brief must be stated here regarding this kind of idolatry. The externals of the Church to be established among the Israelite nation consisted of all those things the Lord told Moses to make, when he was on Mount Sinai. These were the tent of meeting together with the ark there, the mercy-seat above it, the table on which the loaves of the Presence were laid, the lampstand, the altar of incense, also the altar of burnt offering, and the garments of Aaron and his sons, in particular the ephod with the breastplate over it. In addition, the anointing oil, the incense, the blood of burnt offerings and of sacrifices, the wine for drink-offerings, the fire on the altar, and much more besides. The Israelite and Jewish nation venerated all these elements as things that were holy, yet without any respect for the holiness they represented. They had no thought at all of the Lord, heaven, love, faith, regeneration, nor thus of the realities meant by those elements. Since their worship was like this it was a worship of pieces of wood, loaves of bread, wine, blood, oil, fire, and garments, but not of the Lord within those objects. That worship as practised by them is not Divine but idolatrous worship, as is self-evident.
