In the 1852 translation of the Psalms into Javanese by Johann F.C. Gericke, the translator attempted to highlight the different voices and sections of the psalm by using different language styles or sociolects of Javanese. Ngoko , a “top-down” register, was used when senior people communicated to people junior in age or rank, and kromo , a “bottom-up” and more ornate register, was used to address superiors and elders. According to Gericke (quoted in Solleveld, cited below) “If one sought to use one and the same language in the entire Psalm, no Javanese would understand it. The difference between Kromo and Ngoko is often as big as between Dutch and Polish.”

• In verse 1 and 2, the psalmist uses kromo
• In verse 3, the enemies of the king in Zion and rebels use ngoko
• In verse 4 and 5, the pslamist again uses kromo
• In verse 6, God himself is quoted in ngoko, but in a style differing from that of the rebels
• In the first half of verse 7, the anointed king speaks kromo
• From the second half of verse 7 and verses 8 and 9, containing the words of the Lord to his Anointed One, ngoko is used again
• In verses 10, 11, and 12, the psalmist uses kromo in his admonition to the rebels.
