Псалтирь 116:1

Look at what's actually on the page: two commands, back to back, aimed at everyone — "all nations... all peoples." Not "all Israel." Not "all who keep the Law." All. This is the entire first verse of what is, in most English Bibles, the shortest psalm in the whole Bible — Psalm 117 has just two verses. In your Synodal Bible it's numbered Псалтирь 116 because Russian tradition follows the old Greek and Latin numbering of the Psalms rather than the Hebrew numbering most English readers use — same words, different label on the drawer. Worth knowing so you're not confused when a friend with an English Bible flips to "Psalm 117" and reads the identical line.

What's easy to miss: an ancient Israelite reading this would have felt the shock of it. Israel knew itself as the chosen, set-apart people — circumcised, given the Law, given the land. And here, tucked into their own hymnbook, is a command for foreigners — the nations who worship other gods, who don't know the covenant — to praise the LORD by his personal, covenant name. This isn't polite religious tolerance. It's a summons. The second half of the psalm (not quoted here, but worth reading) gives the reason: because his mercy toward us is great, and his truth endures forever — the psalmist reasons from God's faithfulness to Israel outward to a claim on the whole earth.

Where this sits in the bigger story: the Psalter keeps circling back to this hope — that Israel's God is not a tribal deity but the King of the whole earth
