Ezekiel 40:39 says, And in the porch of the gate were two tables on this side, and two tables on that side, to slay thereon the burnt offering and the sin offering and the trespass offering. God said that there were to be two tables on each side of the north gate. There was no altar mentioned, but there were several places to prepare for sacrifice. These were to be used for the offerings made to God, which included both the sin and trespass offerings. There is now only one sacrifice offering for all our sins and trespasses, and that is the shed blood of Jesus Christ, but we will worship God in several places until we are at home in heaven. Still, if we are a Christian we will not worship many gods but will only worship one God through putting our faith in Jesus Christ.
Verse forty adds, And at the side without, as one goeth up to the entry of the north gate, were two tables; and on the other side, which was at the porch of the gate, were two tables. There were also to be two tables on each side of the north gate as people went up to it.
Verse forty-one continues, Four tables were on this side, and four tables on that side, by the side of the gate; eight tables, whereupon they slew their sacrifices. There would be a total of eight gates for people to prepare their offerings. We may come to Jesus from many different places, but we as followers of Christ can only come to present our offering, which is our life, to God by putting our faith in Jesus Christ.
Verse forty-two states, And the four tables were of hewn stone for the burnt offering, of a cubit and an half long, and a cubit and an half broad, and one cubit high: whereupon also they laid the instruments wherewith they slew the burnt offering and the sacrifice. Ezekiel was then told the size of four tables, which would be made of stone and used to prepare the burnt offerings brought by the people.
Verse forty-three adds, And within were hooks, an hand broad, fastened round about: and upon the tables was the flesh of the offering. God also said there would be hooks fastened to the tables to hang the sacrifices on. There was no longer an altar mentioned, but the sacrifices were still to be brought. We have no physical altar where we can offer sacrifices to God but come to Him individually through our faith in Jesus Christ as we present ourselves as a living sacrifice.
