OET interlinear HERO (JDG) 11:31

uW Translation Notes:

Note 1 topic: figures-of-speech / synecdoche

אֲשֶׁ֨ר יֵצֵ֜א מִ⁠דַּלְתֵ֤י בֵיתִ⁠י֙ לִ⁠קְרָאתִ֔⁠י

(Some words not found in UHB: and=it_was [that,which]_comes_out which/who comes_out from,the_doors_of my_house_of,my to,meet,me when,return,I in,peace from=(the)_sons ˊAmmōn and=it_was to/for=YHWH and,I,will_offer_it_up burnt_offering )

Jephthah is using one part of his house, its doors, to mean all of the house as a place for human habitation. In other words, he is specifying a person, rather than an animal that might come from a field or a stall. (See the discussion in the Introduction to this chapter of how wrong Jephthah was to offer a human sacrifice and for what purpose the author includes this account in the book of Judges.) Alternate translation: [the first member of my household who comes out to greet me]

(Some words not found in UHB: and=it_was [that,which]_comes_out which/who comes_out from,the_doors_of my_house_of,my to,meet,me when,return,I in,peace from=(the)_sons ˊAmmōn and=it_was to/for=YHWH and,I,will_offer_it_up burnt_offering )

If your language does not use an abstract noun for the idea of peace, you could express the same idea in another way. Alternate translation: [peacefully]
