I came to a question of the book name of Psalms. We say it is Psalms, but the first chapter we call it Psalm 1 (without s). However, for the name of book of Proverbs, we call it Proverbs 1 (with s). Is it correct? Can we say Psalm 1?
Why the book of Psalms have such a special property?
The Hebrew for Proverbs translates to "The Proverbs of Solomon"
The Hebrew for Psalms translates to "Praises". The Septuagint translated it to "Psalms" (see also Luke 20:42; Acts 1:20). The English title comes from the Greek translation. Each individual musical item was called a "Psalm".
On a similar topic, I wish folks would stop referring to "Revelation" as "Revelations". ;)
