Upvote:6
Multiple ways, though not all of them are obvious in the English translation.
Jesus refers to himself with 'I AM' in a manner as to make a direct connection to Yahweh from the Old Testament.
“Very truly I tell you,” Jesus answered, “before Abraham was born, I am!” John 8:58
God said to Moses, “I am who I am. This is what you are to say to the Israelites ‘I am has sent me to you.’” Exodus 3:14

EDIT Somebody wanted more specificity, so if you read the whole passage Jesus says clearly to the Jews...
Jesus replied, “If I glorify myself,(BN) my glory means nothing. My Father, whom you claim as your God, is the one who glorifies me. John 8:54
Doesn't get much clearer than that. The God of the Jews is Yaweh. Jesus says that the God they claim is his Father.
