To “ascend” something is to go up or climb up something (see: Genesis 28:12; 2 Samuel 15:30). The word “ascend” can also be used to talk about rising up into the air. When Jesus returned to heaven he ascended into heaven. That is, he rose into the air and went into the sky (see: Acts 1:9-11; Ephesians 4:8-10; see also: Psalm 68:18). Scholars sometimes call this “the ascension.”
**Advice to translators**: In the Bible, heaven is often spoken about as if it were up and in the sky. Hell was spoken about as if it were down and in the ground.
