I'm trying to reconcile a verse with the actual event timeline.
וַיִּשְׂטֹ֤ם עֵשָׂו֙ אֶֽת־יַעֲקֹ֔ב עַל־הַ֨בְּרָכָ֔ה אֲשֶׁ֥ר בֵּרֲכ֖וֹ אָבִ֑יו וַיֹּ֨אמֶר עֵשָׂ֜ו בְּלִבּ֗וֹ יִקְרְבוּ֙ יְמֵי֙ אֵ֣בֶל אָבִ֔י וְאַֽהַרְגָ֖ה אֶת־יַעֲקֹ֥ב אָחִֽי׃
We see from the above, that Esav was willing to wait until his father died until he would kill Ya'akov.
Ya'akov was in Lavan's home 20 years, as it says:
Genesis 31:41 (from Sefaria):
זֶה־לִּ֞י עֶשְׂרִ֣ים שָׁנָה֮ בְּבֵיתֶךָ֒ עֲבַדְתִּ֜יךָ אַרְבַּֽע־עֶשְׂרֵ֤ה שָׁנָה֙ בִּשְׁתֵּ֣י בְנֹתֶ֔יךָ וְשֵׁ֥שׁ שָׁנִ֖ים בְּצֹאנֶ֑ךָ וַתַּחֲלֵ֥ף אֶת־מַשְׂכֻּרְתִּ֖י עֲשֶׂ֥רֶת מֹנִֽים׃
These twenty years have I been in thy house: I served thee fourteen years for thy two daughters, and six years for thy flock; and thou hast changed my wages ten times.
Did Yitchak die during this period? If not, at what point did he die? If he did, since Esav knew that Ya'akov was in Lavan's home (see Breishit 28:6), why didn't he go after Ya'akov, there?
