Psalm 119:9–16
9 How can a young person stay on the path of purity?
By living according to your word.
10 I seek you with all my heart;
do not let me stray from your commands.
11 I have hidden your word in my heart
that I might not sin against you.
12 Praise be to you, LORD;
teach me your decrees.
13 With my lips I recount
all the laws that come from your mouth.
14 I rejoice in following your statutes
as one rejoices in great riches.
15 I meditate on your precepts
and consider your ways.
16 I delight in your decrees;
I will not neglect your word.
This week we are primarily going to focus on practices related to this text and spend more time than usual in meditation and reflection. But for today lets just look at the big picture overall context of this passage.
Psalm 119 is a masterful piece of poetry in which the care and precision of the author reflects the value of its subject. The whole chapter, which is the longest psalm in the book, is known as an alphabetical acrostic. Each section is designated to a letter of the Hebrew alphabet, your Bible likely indicates that. Each line in that section begins with the section's letter. See the pdf below for a visual of the Hebrew text.
The subject of the whole psalm is the Word of God and the Law. The care and precision the psalmist uses in writing this reflects his care and precision in following it. Throughout the chapter the author uses nine different words to reflect the Word of God and the Law. In the pdf below I've highlighted those different words in blue in the text above and the Hebrew text below. You'll notice that each line contains a reference to the Law. This psalm only includes 8 of the words, neglecting to include the most common word for the Law, torah.
Of course, the psalmist is referencing the Mosaic Law. This topic always brings up questions of the continuity and discontinuity between the Old Testament and the New Testament, the old covenant and the new covenant. I've linked you to some resources below to explore this topic further.
