Matthew 14:27

‘But immediately Jesus spoke to them, saying, “Be of good cheer; it is I; don't be afraid.” '

Jesus immediately sought to remove their fears saying, ‘Take courage, it is I, don't be afraid'. ‘It is I' is ego eimi. In LXX this was also the Name of God revealed to Moses (Exodus 3:14). While it was not Jesus' intention Matthew does, in a context like this, probably intend his readers to take the hint. Compare ‘the Name of the Father, and of the Son, and of the Holy Spirit' (Matthew 28:19).
