John 14:9

Philip and the other disciples had not yet completely realized who Jesus was. They did not understand what John revealed in the prologue of this Gospel, namely, that the Son is the exact representation of the Father (cf. John 1:18). Long exposure to Jesus should have produced greater insight in these disciples. Still that insight is only the product of God’s gracious enlightenment (cf. Matthew 16:17; 1 Corinthians 2:6-16).

"No material image or likeness can adequately depict God. Only a person can give knowledge of him since personality cannot be represented by an impersonal object." [Note: Tenney, "John," p. 145.]

This was another clear claim to deity.
