John 21:4: The disciples knew not that it was yesus

Jesus sometimes by slow degrees
Himself to His disciples shows,
Darkly at first the sinner sees,
Nor yet his distant Saviour knows,
Surrounded with imperfect light
And half discover'd to the sight.

He speaks in tender pitying grace,
Kindly into our wants inquires,
His love's omnipotence displays,
To satiate our enlarged desires;
Feeds with His wonder-working word,
And then we cry, It is the Lord!
