I found this in the book of Genesis:
Ponamque fœdus meum tecum: et ingredieris arcam tu et filii tui, uxor tua, et uxores filiorum tuorum tecum.
....which translates as ....
And I will establish my covenant with thee, and thou shalt enter into the ark, thou and thy sons, and thy wife, and the wives of thy sons with thee.
What does 'foedus' here mean. I can find no translation of 'foedus' that means 'covenant'. ?
