1 Corinthians 1:13-16 discusses baptism into Christ; here baptism into Moses prefigures Christian baptism as a type.

In 1 Corinthians 12:13, Paul applies the same 'all baptized into one' phrase to the church's unity in the Spirit.

Exodus 14:31 describes Israel believing the Lord and Moses after crossing the sea, the event Paul summarizes as baptism into Moses.

Exodus 13:21 describes the pillar of cloud that led Israel—the same cloud Paul says they were baptized into.

Nehemiah 9:19 recalls the pillar of cloud guiding Israel by day—the same cloud from the baptism reference here.

Psalm 78:13 recounts the sea parting—the very sea Paul says the Israelites were baptized into with Moses.

Psalm 105:39 describes the cloud as a covering—the same cloud Paul refers to as part of their baptism into Moses.
