Not only are certain animals unclean for food, but they also can make a person unclean if he touches them (often whether they are dead or alive; Chapter 11). This too is to set the Hebrews apart from other peoples and to teach them the importance of being ritually clean and morally righteous before God. But too many got caught up in the intricacies of the laws of uncleanness and entirely missed the point of God’s lesson.
SOME things that make one unclean are not sinful (using the toilet, disposing of an animal that has died, . . . ) but some are. But being unclean prohibits one from certain worship activities.
12:8 is the verse that informs us when we get to the New Testament that Jesus’ family was not rich. Mary offered two turtledoves, not a lamb (Luke 2:22-24).
Chapter 13 deals much with leprosy. This is not necessarily leprosy as we know it, but generally any potentially contagious skin ailment. This is also the source for the quarantining of individuals with potentially devastating diseases–despite what many might say today. Better the inconvenience of a few than the death of all!
It’s refreshing to know that baldness is not uncleanness (13:40-41)!!
In the latter half of Psalm 25 David comments that the Lord instructs those who fear Him and causes their descendants to inherit the land that God has promised. The secret, or counsel, or intimacy of the Lord (verse 14) is for those who fear Him.
