John Gill Commentary Psalms 119:164

"Seven times a day do I praise thee, Because of thy righteous ordinances." — Psalms 119:164 (ASV)

Seven times a day I praise you
That is, very often in a day; not a day passed over his head but he praised the Lord, and often in the day; so the phrase "seven times" is used, (Psalms 12:6) (Proverbs 24:16) . Praise is comely for the saints, delightful and well pleasing to God, being offered up in faith and through Christ; and should be frequent, since our mercies, temporal and spiritual, are daily renewed; and therefore we should always, in everything, for everything, and at all seasons, give thanks to God, (Ephesians 5:20) (1 Thessalonians 5:18) ;

because of your righteous judgments :
either upon his enemies, the persecuting princes, as Aben Ezra; so saints may, should, and will praise the Lord, for his righteous judgments on the enemies of his church and people, because not only of their deliverance from them, but because of the honour of his justice, and the glory of his name; see (Revelation 18:20) (Revelation 19:1Revelation 19:2) ; or because of the word of God, the precepts, ordinances, and doctrines of it, which are all righteous; for his knowledge of them, and for the benefit and comfort received from them; see (Psalms 119:7Psalms 119:20) .
