Mathusalem vécut, après avoir engendré Lamec, sept cent quatre-vingt-deux ans; il eut encore des fils et des filles.
Rashi
בני עלית THOU WENTEST UP, O MY SON — from that murderous deed you withdrew saying, (Genesis. 5:26) “what profit is it if we slay our brother”, and similarly did he act when Tamar was condemned to death, for he said “She is righteous: mine is the blame” (cf. Rashi on Genesis 38:26), therefore as a reward כרע רבץ HE STOOPED DOWN, HE CROUCHED etc. — as we are told of the days of Solomon (1 Kings 5:5) “[Israel dwelt safely] every man under his vine etc.” (Genesis Rabbah 99:8).
Rashi
ותגנב אתי — means thou didst steal away my mind (as in Genesis 5:26).
