Jehovah is always His name in Israel, and that of government, save in a few cases where Adonai (Lord is the proper appellative use of it) is employed. But it is to be noticed that Jehovah is used in Proverbs, because it is authoritatively instructive in known relationship; never in Ecclesiastes, where it is God in contrast with man having his own experience as such on earth. “God” abstractedly is only once used in Proverbs (xxxv. 2). We have “her God” in chapter 2:17.
