In Mark 10, which two disciples asked to sit at Jesus' right and left in his glory?

Answer: James and John

James and John, the sons of Zebedee, asked for the seats; the other ten became indignant with them.

“Then James and John, the sons of Zebedee, came to Jesus and declared, “Teacher, we want You to do for us whatever we ask.” “What do you want Me to do for you?” He inquired. They answered, “Grant that one of us may sit at Your right hand and the other at Your left in Your glory.””— Mark 10:35-37 (BSB)
