Prayers, Songs, Praises: Psalm 19

The Witness of Creation and Scripture
For the choir director. A psalm of David.

19:1 The heavens declare the glory of God,
and the expanse proclaims the work of his hands.
2 Day after day they pour out speech;
night after night they communicate knowledge.
3 There is no speech; there are no words;
their voice is not heard.
4 Their message [LXX, Sym, Syr, Vg; MT reads line] has gone out to the whole earth,

and their words to the ends of the world.
In the heavens he has pitched a tent for the sun. 
5 It is like a bridegroom coming from his home;
it rejoices like an athlete running a course.
6 It rises from one end of the heavens
and circles to their other end;
nothing is hidden from its heat.

7 The instruction of the Lord is perfect,
renewing one’s life;
the testimony of the Lord is trustworthy,
making the inexperienced wise.
8 The precepts of the Lord are right,
making the heart glad;
the command of the Lord is radiant,
making the eyes light up.
9 The fear of the Lord is pure,
enduring forever;
the ordinances of the Lord are reliable
and altogether righteous.
10 They are more desirable than gold—
than an abundance of pure gold;
and sweeter than honey
dripping from a honeycomb.
11 In addition, your servant is warned by them,
and in keeping them there is an abundant reward.

12 Who perceives his unintentional sins?
Cleanse me from my hidden faults.
13 Moreover, keep your servant from willful sins;
do not let them rule me.
Then I will be blameless
and cleansed from blatant rebellion.
14 May the words of my mouth
and the meditation of my heart
be acceptable to you,
Lord, my rock and my Redeemer.

note: 

LXX = Septuagint

The Septuagint is a translation of the Hebrew Bible into Greek, done in about the 2nd and 3rd centuries BC so that those who did not understand Hebrew could have a Bible written in a language they could understand. At that time, the Greek language was becoming more and more common. The Roman numeral (Latin) LXX is 70. Tradition has it that approximately 70 Jewish scholars did this translation.

SYM = Symmachus

The Symmachus is an ancient Greek translation created in the 2nd century AD by Symmachus the Ebionite, known for its readability in its time.

SYR = Syriac

Syriac refers to a translation created in the 2nd to 5th century AD into the Syriac dialect of Aramaic. It's helpful for determining exact meanings of original words, as it is close to Hebrew and Aramaic languages of the Bible.

VG = Vulgate

The Vulgate is a late 4th-century AD Latin translation of the Bible primarily done by the Christian scholar and early Church father Jerome. The Vulgate became the official Latin Bible of the Catholic Church used for centuries. It is used in more current translations to see how early Christians understood ancient text.

MT = Masoretic Text

The Masoretic Text is the authoritative Hebrew and Aramaic text of the Old Testament maintained by Jewish scribes (the Masoretes). Most English Old Testament translations use the MT as their basis for the Old Testament.

The footnote for 19:4 reads: LXX, Sym, Syr, Vg; MT reads line. 

There are commas separating LXX, Sym, Syr, and Vg, but a colon separating those four from MT. This indicates that the first four translations have similar meanings, while the MT reads something different.

According to Ellicott's Commentary for English Readers, Their line  may refer to a plumb line or measuring cord.
 

Prayers, Songs, Praises: Psalm 18:25-50

18:25 With the faithful
you prove yourself faithful,
with the blameless
you prove yourself blameless,
26 with the pure
you prove yourself pure,
but with the crooked
you prove yourself shrewd.
27 For you rescue an oppressed people,
but you humble those with haughty eyes.
28 Lord, you light my lamp;
my God illuminates my darkness.
29 With you I can attack a barricade,
and with my God I can leap over a wall.

30 God—his way is perfect;
the word of the Lord is pure.
He is a shield to all who take refuge in him.
31 For who is God besides the Lord?
And who is a rock? Only our God.
32 God—he clothes me with strength
and makes my way perfect.
33 He makes my feet like the feet of a deer
and sets me securely on the heights.
34 He trains my hands for war;
my arms can bend a bow of bronze.
35 You have given me the shield of your salvation;
your right hand upholds me,
and your humility exalts me.
36 You make a spacious place beneath me for my steps,
and my ankles do not give way.

37 I pursue my enemies and overtake them;
I do not turn back until they are wiped out.
38 I crush them, and they cannot get up;
they fall beneath my feet.
39 You have clothed me with strength for battle;
you subdue my adversaries beneath me.
40 You have made my enemies retreat before me;
I annihilate those who hate me.
41 They cry for help, but there is no one to save them—
they cry to the Lord, but he does not answer them.
42 I pulverize them like dust before the wind;
I trample them like mud in the streets.

43 You have freed me from the feuds among the people;
you have appointed me the head of nations;
a people I had not known serve me.
44 Foreigners submit to me cringing;
as soon as they hear they obey me.
45 Foreigners lose heart
and come trembling from their fortifications.
46 The Lord lives—blessed be my rock!
The God of my salvation is exalted.
47 God—he grants me vengeance
and subdues peoples under me.
48 He frees me from my enemies.
You exalt me above my adversaries;
you rescue me from violent men.
49 Therefore I will give thanks to you among the nations, Lord;
I will sing praises about your name.
50 He gives great victories to his king;
he shows loyalty to his anointed,
to David and his descendants forever.
