Leviticus 26:18

And if ye will not yet for all this hearken unto me. — Better, and if up to these ye will not hearken unto me, that is, if they should persist in their disobedience to the very end of those punishments mentioned in Leviticus 26:16. This verse, therefore, introduces the second degree of punishments, which ends with Leviticus 26:20.

I will punish you seven times more. — That is, indefinitely or unceasingly; many more times. Seven being a complete number is often used to denote thoroughness (see Note on Leviticus 4:6), a large or indefinite number. Hence the declaration “He shall deliver thee in six troubles; yea, in seven there shall no evil touch thee” (Job 5:19), and “if he trespass against thee seven times in a day” (Luke 17:4), that is, an indefinite number of times. (Comp. also Psalms 119:164; Proverbs 24:16, &c.)
