Ulangan 10:10

10:10 As for me, I stayed at the mountain as I did the first time, forty days and nights. The Lord listened to me that time as well and decided not to destroy you.

Ulangan 16:4

16:4 There must not be a scrap of yeast within your land ¹  for seven days, nor can any of the meat you sacrifice on the evening of the first day remain until the next morning. ² 

[16:4]  ¹ tn Heb “leaven must not be seen among you in all your border.”

[16:4]  ² tn Heb “remain all night until the morning” (so KJV, ASV). This has been simplified in the translation for stylistic reasons.
