Verbs are nominative-aligned; all nouns and third-person pronouns are ergative-aligned. Hence <hëkp> is in the absolutive state, being the second object of <lyeçhôp>, while bôpeyð is in the accusative case because it is a first-person pronoun.

Lelôplū=ða is a single verb here rather than a verb + a preposition, so Xad is the direct object and takes the absolutive case.
