Reference for Shevuot 41:1

קמ"ל כדשני ליה

<br> therefore he teaches us [that he is punished by stripes] as Abaye answered him. And if you will, I may say, that just as he brings an offering for a false oath, so he brings an offering for a vain oath; and it is in accordance with R. Akiba's view who makes him liable for [an oath in] the past as in the future. <br>
