Psalm 5:7, 10

Recently, I started over in my daily reading of Psalms and Proverbs.  I had been alternating between the ESV and the NIV, but this time, I'm reading the NKJV, which I'm not very familiar with.  Last week, I read Psalm 5 and noticed a contrast I'd never seen before.  In verse 7, the Psalmist writes, "I will come into Your house in the multitude of Your mercy," and in verse 10, he says, "cast them [his enemies] out in the multitude of their transgressions."  The word multitude (בְּרֹב in Hebrew) is used in both verses, which highlights the contrast between "come into" and "cast... out" and between "Your mercy" and "their transgressions."
