מַהֲרוּ֮ וַעֲל֣וּ אֶל־אָבִי֒ וַאֲמַרְתֶּ֣ם אֵלָ֗יו כֹּ֤ה אָמַר֙ בִּנְךָ֣ יוֹסֵ֔ף שָׂמַ֧נִי אֱלֹהִ֛ים לְאָד֖וֹן לְכָל־מִצְרָ֑יִם רְדָ֥ה אֵלַ֖י אַֽל־תַּעֲמֹֽד׃
당신들은 속히 아버지께로 올라가서 고하기를 아버지의 아들 요셉의 말에 하나님이 나를 애굽 전국의 주로 세우셨으니 내게로 지체말고 내려오사
Rashi
ועלו אל אבי AND GO UP TO MY FATHER — he said “go up” because the land of Israel is situated higher than all the neighbouring countries (Kiddushin 69a).
Chizkuni
רדה אלי, “come down to me!” he did not say: רד “come down”, which has the the numerical value of 204, but said רדה is the numerical value of 209, to indicate that the 210 years decreed for the Israelites stay in Egypt had already started i.e. we are already within the 210 years decreed for the Israelites stay in Egypt so that the exile would not be lengthened by Yaakov and family resettling in Egypt without delay. There are only 209 of these years left.
