Bereshit 31:4

ויקרא לרחל וללאה AND HE CALLED RACHEL AND LEAH — First Rachel and afterwards Leah for she was the chief wife of the house for whose sake Jacob had entered into relations with Laban. Even the descendants of Leah admitted this (that Rachel was the principal wife), for Boaz and his Law-Court who were of the Tribe of Judah (Leah’s son) said (Ruth 4:11) “like Rachel and like Leah which two did build etc.”, mentioning Rachel before Leah (Genesis Rabbah 71:2).

And Ya῾aqov sent and called Raĥel and Le᾽a to the field to his flock,

וַיִּשְׁלַ֣ח יַעֲקֹ֔ב וַיִּקְרָ֖א לְרָחֵ֣ל וּלְלֵאָ֑ה הַשָּׂדֶ֖ה אֶל־צֹאנֽוֹ׃
