John 14:13 restates the same promise with added purpose: that the Father be glorified. It reinforces the 'ask in my name' principle.

John 16:23 shifts focus from asking Jesus to asking the Father in Jesus' name. Clarifies the prayer dynamic.

Matthew 7:7 is Jesus' earlier teaching on asking and receiving, directly parallel to the promise here to do whatever you ask in His name.

Matthew 18:19 adds the condition of agreement in prayer, complementing the promise here of asking in Jesus' name.
