Yahweh, My Vindicator
Psalm 26 is a "Lament Psalm." The circumstance in which David wrote the Psalm is not certain but is likely that the nation was facing some kind of calamity. In Psalm 25, David contrasts his character with God's and ends up confessing his sin. In Psalm 26, David contrast his character with that of the ungodly and declares himself to have integrity.
This Psalm can be divided into two parts:
1) David vindicates his behavior (1-7)
2) David vindicates his worship (8-12)
Observation: David does not fear exposure; he is ready to change any wrong. He asks the Lord to “prove," “try," and “test" him instead of appealing to liars for their perspective. Second, David requests that his love for God's presence would spare him the fate of sinners.
Purpose: To show us how to pray, allowing God to examine us and then vindicate us so we can be washed and live from and in His faithfulness.
Yahweh, My Light and Salvation
Psalm 27 is a "Lament Psalm." When David wrote it is not completely clear; however the Greek translation of the Hebrew Bible adds the words, “before he was anointed" to the superscript. David was anointed three times: by Samuel, by Judah at Hebron, and by all of Israel. Likely, this Psalm was written by David before his third anointing, in a time of growing and robust faith, possibly before the civil war with Israel.
This Psalm can be divided into three units:
1) The confidence of faith (1-3)
2) The challenge of faith (7-12)
3) The conquest of faith (13-14)
Observation: David finds all his confidence as he hides out in Yahweh's house. His confidence is then challenged when he ponders the faithlessness of others who have deserted and slandered him. He then determines to triumph on in his commitment to wait on Yahweh.
Purpose: To show how to pray in faith, devoted to your real home--God's presence--when facing the challenges of betrayal, desertion, and slander.
