'Look' in the Bible

The next day John saw Jesus coming towards him and exclaimed, "Look, that is the Lamb of God who is to take away the sin of the world!

when he saw Jesus passing by, and said, "Look! that is the Lamb of God!"

Jesus saw Nathanael approaching, and said of him, "Look! here is a true Israelite, in whom there is no deceitfulness!"

Do you not say, 'It wants four months yet to the harvest'? But look round, I tell you, and observe these plains-- they are already ripe for the sickle.

When however the crowd saw that neither Jesus nor His disciples were there, they themselves also took boats and came to Capernaum to look for Jesus.

You will look for me and will not find me, and where I am you cannot come."

What do those words of his mean, 'You will look for me, but will not find me, and where I am you cannot come'?"

And again another Scripture says, "They shall look on Him whom they have pierced."
