Vine's Expository Dictionary of NT Words

whence Eng. words beginning with "hept," corresponds to the Heb. sheba' (which is akin to saba', signifying "to be full, abundant"), sometimes used as an expression of fullness, e.g., Ruth 4:15 : it generally expresses completeness, and is used most frequently in the Apocalypse; it is not found in the Gospel of John, nor between the Acts and the Apocalypse, except in Hebrews 11:30 (in Romans 11:4 the numeral is heptakischilioi, "seven thousand"); in Matthew 22:26 it is translated "seventh" (marg., "seven").

Note: In 2 Peter 2:5 , RV, "Noah with seven others" is a translation into idiomatic English of the Greek idiom "Noah the eighth person" (so AV, translating literally). See EIGHT.
