See to it that you do not refuse [to listen to] Him who is speaking [to you now]. For if those [sons of Israel] did not escape when they refused [to listen to] him who warned them on earth [revealing God’s will], how much less will we escape if we turn our backs on Him who warns from heaven?

not forsaking our meeting together [as believers for worship and instruction], as is the habit of some, but encouraging one another; and all the more [faithfully] as you see the day [of Christ’s return] approaching.
