1 Corinthians 10 v 2


1 Corinthians 10:2 
And were all baptized unto Moses in the cloud and in the sea; 


10:2. Third, the Israelites were all baptized into Moses, that is, united with their spiritual head, God’s servant, who became the object of their trust (Ex. 14:31; cf. John 5:45). The Corinthians had been baptized into the body of Christ (1 Cor. 12:13) of which He is the Head (Eph. 1:22) and in whom they trusted (Matt. 12:21; Eph. 1:12).
