Reference for Leviticus 4:4

וְהֵבִ֣יא אֶת־הַפָּ֗ר אֶל־פֶּ֛תַח אֹ֥הֶל מוֹעֵ֖ד לִפְנֵ֣י יְהוָ֑ה וְסָמַ֤ךְ אֶת־יָדוֹ֙ עַל־רֹ֣אשׁ הַפָּ֔ר וְשָׁחַ֥ט אֶת־הַפָּ֖ר לִפְנֵ֥י יְהוָֽה׃

And he shall bring the bullock unto the door of the tent of meeting before the LORD; and he shall lay his hand upon the head of the bullock, and kill the bullock before the LORD.
