He measured it on the four sides; it had a wall all around, five hundred cubits long and five hundred wide, to separate the holy areas from the common. (Ezekiel 42:20, NKJV)
Ezekiel’s visionary temple (Ezekiel 40-43) was measured by a man whose appearance was like bronze and who had “a measuring rod in his hand” (Ezekiel 40:3). Ezekiel was to look, listen, and fix his mind on everything God showed him in the vision so he could tell the house of Israel everything he saw (Ezekiel 40:4). This is not a literal temple to be built sometime in our future. It is a figurative, prophetic description of the temple of God that exists today, the church (Ephesians 2:19-22). The description of this temple was to cause Israel to “be ashamed of their iniquities” as they “measured the pattern” (Ezekiel 43:10, 11). Notably, Ezekiel’s temple is distinguished by the presence of God’s glory and by its holiness (Ezekiel 43:1-5, 12). The wall surrounding the temple marks a separation between holy places and what is common or profane (Ezekiel 42:20). God, who is holy, demands that His people are also holy (1 Peter 1:15-16). Defiled priests could not serve in Israel’s tabernacle and temple (Leviticus 21). Neither can Christians (who are priests in God’s house) serve God with defiled hearts, hands and lives (1 Peter 2:1-12). To dwell with God we must come out of sin and live separately unto Him (2 Corinthians 6:17-7:1).
