4 Against thee, thee only, have I sinned, and done this evil in thy sight: that thou mightest be justified when thou speakest, and be clear when thou judgest.
David acknowledges that his sin was only against God. He’s done it in God’s sight. God has seen him so God will be just when He passes down judgment on David. This goes back to what we were talking about in the last section. The important fact of understanding that when we sin, we sin against God. When we do something wrong to somebody else, we’re actually doing that wrong to God. David could have looked at his sin as a sin against Bathsheba since he took her in adultery. Or he could have looked at it is a sin against Uriah because he had him killed. And I’m sure that at first he thought that his only wrong doing was against these two.. But when Nathan came into the room and told him he was the man, he realized he had sinned against God and God had seen the whole thing. Funny how sin makes us forget that God is watching. Let’s make sure we don’t forget that
5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
David realizes that when he was conceived, he was conceived in sin. This is a very interesting statement and one that a lot of people don’t understand even today. I’m not sure what teaching or belief David had that was behind this statement, but each of us should know about original sin. The fact that Adam disobeyed in the garden and then his seed was passed on to every human being. That was the seed of sin. This is what David is talking about here. We are all conceived in sin.
It doesn’t matter whether you’re leading a righteous life and have never done a single thing wrong. Sin is within you because of Adam’s seed. It is passed down from generation to generation. There is no escaping the seed of sin. However Jesus was born of a virgin. The Holy Spirit impregnated Mary, not a man. So Jesus did not have Adam’s seed within him and therefore H did not have sin. Because of this He could be our perfect sacrifice for sin. And because he was a perfect sacrifice our sins are washed as white as snow. It is up to each one of us to accept His sacrifice for our own sins. We must acknowledge our sins, confess them, repent, and accept His sacrifice. It’s a matter of heaven or hell!
6 Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.
7 Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.
David realizes that God wants him to be truthful from the very center of his being. Have you opened up every door of your life to God? Have you allowed Him access into the shady places in your life? In Revelations, Jesus said I stand at the door and knock (Rev 3:20). He is knocking at the door to our heart wanting the truth. Now God knows what’s in our heart, but he wants to make sure we know what’s in our heart! Remember, your heart will deceive you (Jer 17:9) And God will reveal our heart to us if we just ask. He will give us wisdom to deal with those areas of our lives that are out of line if we ask him too.
Hyssop was used to sprinkle blood on the sacrifices that the priests were giving in the Old Testament. It is an herb branch that would be dipped in the blood of the sacrifice, and then the blood would be sprinkled on the altar. It’s signified the covering of blood that was needed for all sin. David knows the value of being purged with hyssop. He knows that this can make him clean. Only by blood can sin be cleansed. And the blood washes as white as snow. I know that doesn’t make sense in the natural but in the spiritual it is one of the things that we are most thankful for. Jesus blood cleanses us from all unrighteousness
8 Make me to hear joy and gladness; that the bones which thou hast broken may rejoice.
9 Hide thy face from my sins, and blot out all mine iniquities.
David, in the midst of his suffering over the sin that he committed, wants God to restore his joy his gladness. Isn’t that just like David – wanting to praise the Lord even now. He says that it’s like his bones are broken it hurts so bad, but he still wants to praise the Lord. What a marvelous lesson this is for us! In the middle of the biggest trials, we need to praise God and give him the glory
One more time in verse 9 David asks God to hide his face from the sin that he has committed. He also asks God to blot out his iniquities one more time. David’s not afraid to keep going back to God with the same request over and over again. There’s a lesson to be learned there too. Never grow weary in asking God to forgive you when you’ve done something wrong. He loves you so much.
