'In My Name' in the Bible

and He told them, “Whoever welcomes this child in My name welcomes Me; and whoever welcomes Me [also] welcomes Him who sent Me; for the one who is least among all of you [that is, the one who is genuinely humble—the one with a realistic self-view]—he is the one who is [truly] great.”

He said, “Be careful and see to it that you are not misled; for many will come in My name [appropriating for themselves the name Messiah which belongs to Me alone], saying, ‘I am He,’ and, ‘The time is near!’ Do not follow them.
