In this article, the author draws attention to translation issues, especially related to the avifauna lexis which appears on the pages of the Bible in the analyzed fragment of Job 28:7 in selected twelve Czech and eighteen Polish translations of the Holy Scripture. In the confrontational-lexical analysis, he describes not only the similarities, but above all the noticeable differences, i.e. changes in the equivalence of bird names and how and in what language form depending on the translation version this conceptual category of birds is used in translation by synonymous lexemes. The marginal presence of the Czech lexeme ostříž was noted. The remaining birds mentioned in Job 28:7 have so different lexical equivalents in individual Czech and Polish biblical translations that on the one hand it gives the impression of chaos, and on the other, reveals far-reaching freedom in translating avifaunic names.
