Leviticus 12 is a short chapter that deals with childbirth.  A woman would be isolated for a period of time, for her "purification"  and then a sacrifice would be presented. This purification period was 33 days for a male and 66 days for a female child.   A male child would be circumcised on the 8th day. This sounds like a judgement, but would actually be a blessing to a new mom, wouldn't it? A month or two with the new baby... God is good!

Chapter 13 is a long chapter dealing with leprosy - tzara'at - it is quite detailed.  The person who had any skin issues was to report to the priests.  It was the priests responsibility to examine and determine the treatment of the condition. This may result in the person coming back several times to see if there was any changes. The final decision then would be "clean" or "unclean".  They would also deal with articles of clothing, etc.  The priests had a lot on their hands!

The Complete Jewish study Bible adds an interesting commentary about leprosy.  According to rabbinical writings it was understood that "the practice of gossip or slander opens the door for both spiritual and physical oppression and illness."   Miryam spoke against Moses and the Lord struck her with leprosy... words matter.   James wrote about the tongue and how lack of control there indicates a worthless religion. ( James 1:26)

Psalm 34:13 "Keep your tongue from evil, and your lips from speaking deceit." 
Psalm 39:1 says, "I said, 'I will guard my ways, that I may not sin with my tongue; I will guard my mouth as with a muzzle..."
And Psalm 141:3 gives us this prayer, " Set a guard, O Lord, over my mouth; Keep watch over the door of my lips." 

Proverbs hits these truths about guarding the tongue and our words also, for example:
13:3 "The one who guards his mouth preserves his life; the one who opens wide his lips comes to ruin." 
12:14 " A man will be satisfied with good by the fruit of his words.... " 
And 12:18 "There is one who speaks rashly like the thrusts of a sword, but the tongue of the wise brings healing."
And many more...

Father in heaven, You have taught us that words matter.  There are consequences for speaking out of evil hearts and there are rewards of grace for speaking in kindness and love and truth.  May we speak carefully, and give glory to You.  Help us to guard our tongues this day.  May we learn this important truth I pray, in Jesus' name. amen.
