What does the word “day” [ _yom_ ] mean in other parts of the Holy Bible?

Beyond the creation account, the Holy Bible often uses the term “day” in a broader sense than the time span of twenty-four hours. For example, the Psalmist says, “For a day in Your courts is better than a thousand” (Ps. 84:10; cf. Ps. 90:4; 2 Pet. 3:8). In fact, the word “day” in the Holy Bible can have many meanings. Another of its possible meanings is “eternity,” as when the Father tells the Son, “You are My Son, today I have begotten You” (Ps. 2:7; Acts 13:32; Heb. 1:5). God was also called “the Ancient of Days” (Dan. 7:9) meaning, “the eternal.” And “day” signifies an eternity that transcends time in the phrase: “the day of the Lord” (Acts 2:20), which refers to His second coming. Thus, it is said of the Lord Christ, “our Lord and Savior Jesus Christ. To Him be the glory both now and forever” (2 Pet. 3:18 NKJV).¹¹⁴⁴
