Here's one (among quite a few).
John 14:14
If you ask Me anything in My name, I will do it.
This demonstrates the Lord Jesus is the proper recipient of prayer.
Since only God is to be prayed to proves the Lord Jesus is God.
The 'Me' does not appear in the KJV.
Actually, that reading (the inclusion of "Me", in John 14:14) is an error, precisely because we are told to pray to the Father, not to Jesus. Of course, the Lord is not going to scold us for praying to Jesus, still it is a slight error and contradicts Jesus' own instructions on the principles according to which we are to pray.
Matt. 6:6 (WPNT) But you, whenever you pray, go into your room, and having shut the door
pray to your Father who is in secret; and your Father who sees in secret will repay you openly.
Matt. 6:7-15 (WPNT)
7 “But when you pray do not babble like the heathen; for they think that they will be heard for their many words.
8 So do not be like them, because your Father knows what you need before you ask Him.
9 Therefore, you
pray like this: ‘Our Father who is in the heavens, let Your name be reverenced;
10 let Your kingdom come, let Your will be done, on the earth just as in heaven.
11 Give us today our daily bread;
12 and forgive us our debts, as we also forgive our debtors.
13 And do not bring us into testing, but rescue us from the evil one; because Yours is the kingdom and the power and the glory forever. Amen.’
14 For if you forgive people their trespasses, your heavenly Father will also forgive you.
15 But if you do not forgive people their trespasses, neither will your Father forgive your trespasses.
