Genesis 2:17
16 Then the Lord God commanded the man, “You may freely eat fruit from every tree of the orchard, 17 but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will surely die.” 18 The Lord God said, “It is not good for the man to be alone. I will make a companion for him who corresponds to him.”
Leviticus 15:31
29 Then on the eighth day she must take for herself two turtledoves or two young pigeons, and she must bring them to the priest at the entrance of the Meeting Tent, 30 and the priest is to make one a sin offering and the other a burnt offering. So the priest is to make atonement for her before the Lord from her discharge of impurity. 31 “‘Thus you are to set the Israelites apart from their impurity so that they do not die in their impurity by defiling my tabernacle which is in their midst. 32 This is the law for the one with a discharge: for the one who has a seminal emission and becomes unclean by it,
Notes and References
"... Also developing the conceptual connection between Leviticus 11 and Genesis 2–3 are the implications that stem from disobedient eating of prohibited items. For Adam the forewarned consequence was death (Genesis 2:17), a penalty that resulted in expulsion from the Garden (3:23–24). In a realm removed from the life - giving presence of YHWH physical demise was inevitable (3:19; compare 5:5). The penalty in Leviticus 11 is conceptually similar. Animals forbidden for consumption are declared to be “unclean ... for you” (verses 4–8, 26–28, 31, 35, 38). Touching the carcasses of these disallowed creatures - by extension, including the touching required to ingest them - rendered one “unclean until evening”. Becoming unclean, however, made one inadmissible to the tabernacle (compare Leviticus 15:31). In other words, unclean Israelites found themselves effectively banished from YHWH’s sanctuary presence. The penalty for eating proscribed food thus functionally separated Israelites from YHWH in a manner analogous to Adam and Eve’s banishment as consequence for a similar infraction ..."
