سَبْعُونَ

[Seventy;] a well-known number; (K;) the round number that is between سِتُّونَ and ثَمَانُونَ. (TA.)

The Arabs also use it as meaning [Seventy or more; or] many. (TA.) Thus it is used in the Qur'an, 9:81, where it is said, إِنْ تَسْتَغْفِرْ لَهُمْ سَبْعِينَ مَرَّةً فَلَنْ يَغْفِرَ اللّٰهُ لَهُمْ, meaning If thou beg forgiveness for them many times, even then God will not forgive them; not that God would forgive them if forgiveness were begged more than seventy times: (Bd, * TA:) and سَبْعَةٌ and سَبْعُمِايءَةٍ and the like are used in the same manner. (Bd.)

[Also Seventieth.]
