put my hope in your word

Psalm 119:49-88
Your promise preserves my life.
Though the wicked bind me with ropes, I will not forget your law.
Do good to your servant according to your word, O Lord. Teach me knowledge and good judgment, for I believe in your commands. Before I was afflicted I went astray, but now I obey your word.
Though the arrogant have seared me with lies, I keep your precepts with all my heart.
May those who fear you rejoice when they see me, for I have put my hope in your word.
My soul faints with longing for your salvation, but I have put my hope in your word.
He uses then different words to describe it : God's law, his testimonies(instruction), precepts, status, commandments, ordinances)decrees), word, ways(paths), promises and judgments(rules).
In the psalm we see how eagerly and persistently he applies himself to the task of understanding the law. He learns it by heart. He longs for more. Nothing is allowed to deflect him from it.
The psalm's focus on the truly happy life as one deep-rooted in reverence for God connects it with other's wisdom' psalms.
Why?
Do good and right witness to honor the Lord when people sees me, they will know  that my hope in God's word and Christian sees rejoice.
Though other astray or they bind me with rope, I still obey words of God, the avenge is belong to the Lord, the Lord will do penalty to wick one.
How?
O Lord, teach me knowledge and good judgment, for I believe in your commands.
