Exodus 16:9

Before the Lord; either before the cloudy pillar, where God was especially present; or in the place of God's worship. For though the great tabernacle was not yet built, yet it seems from Exodus 33:7 there was a little tabernacle. For as the solemn, and public, and sabbath worship was among them before the tabernacle was built, so it was necessary. there should be some place where they did assemble together, and perform that worship which was proper to those times, and there God was supposed to be present in a peculiar manner.
