Seder Hayom by: Rabbi Moshe Ben Machir, 1599
...בְּשַׁחַר צָרִיךְ אָדָם לוֹמַר מוֹדֶה אֲנִי לְפָנֶיךָ ײ֨ אלדי ואלדי אֲבוֹתַי שֶׁהוֹצֵאתָנִי מֵאֲפֵילָה לְאוֹרָה. בְּמִנְחָה צָרִיךְ אָדָם לוֹמַר מוֹדֶה אֲנִי לְפָנֶיךָ ײ֨ אלדי ואלדי אֲבוֹתַי כְּשֵׁם שֶׁזְּכִיתָנִי לִרְאוֹת הַחַמָּה בְמִזְרָח כַּךְ זָכִיתִי לִרְאוֹת בְּמַעֲרָב. בָּעֶרֶב צָרִיךְ לוֹמַר יְהִי רָצוֹן מִלְּפָנֶיךָ ײ֨ אלדי ואלדי אֲבוֹתַי כְּשֵׁם שֶׁהָיִיתִי בָּאֲפֵילָה וְהוֹצֵאתָנִי לְאוֹרָה כַּךְ תּוֹצִיאֵנִי מֵאֲפֵילָה לְאוֹרָה.
...In the morning, one must say: I thank you, o Eternal, my God and God of my fathers, that you led me from darkness to light. At Minḥah, one must say: I thank you, o Eternal, my God and God of my fathers, that just as You let me see the sun in the East, so I could see it in the West. In the evening, one must say: May it be Your pleasure, o Eternal, my God and God of my fathers, that just as I was in darkness and You led me into light, so may You lead me from darkness into light.
