Leviticus 19:19 ‘You shall keep My statutes. You shall not let your livestock breed with another kind. You shall not sow your field with mixed seed. Nor shall a garment of mixed linen and wool come upon you.

God is giving the Edah or Community of Israel instructions to be separate from nations who did these things as a part of their pagan religions. While these prohibitions no longer apply, this ordinance still speaks to us today as visual examples of being separate. In the instance of speech, it is the physical manifestation of the thought which is the outflow of what is in our hearts … So it is either the evidence of corruption within us or it is evidence of the goodness of God within us.

Romans 7:22 (NKJV) For I delight in the law of God according to the inward man.

And so, when something comes out of our mouths that shouldn’t have, we should first ask Jesus for forgiveness, then prayerfully examine that external evidence of something internal and make life changes as we need. Perhaps you can follow that trail of evidence to a certain kind of music you listen to and then the appropriate response is to remove that music from your life. God has given us a new nature and that new nature produces new and better things so we need to let go of the old things and embrace the new and better things of God.

Proverbs 4:23 (NKJV) Keep your heart with all diligence, For out of it spring the issues of life.

The Hebrew word for “keep” in Proverbs 4:23 is Nasar and it means to maintain … Which is the work of two additional Hebrew words Shamar and Zamar. Shamar means to guard or protect and Zamar means to prune. When we guard our hearts we keep what shouldn’t get in on the outside, and we also protect what is desirable and is already inside. When we prune our hearts we are willing to trim away those branches so to speak that are not producing good things and because we prune, growth and fruitfulness are accelerated. The Hebrew word Shema is related to Shamar and means “to hear” or to allow something to come into yourself through the portal of your ears … And so even as we prune, we should take care that we are not allowing other things into our hearts that don’t belong; guarding and maintaining and pruning our hearts. When we Shamar or guard our hearts and we Zamar prune our hearts then we are Nasar, maintaining our hearts. Biblically speaking, the heart is the core of everything; the seat of the will and the moral life and the location of the intellect.  The Hebrew word for heart is Lev, which is created using a lamed and a bet … In ancient Hebrew, the lamed is a pictograph for a cattle goad (a small spear that kept the cattle moving forward) and the bet for a house. So then, the reason we should maintain our heart with guarding and pruning is because it is that which moves and directs the house of our bodies.
