Bible21 translates the original Hebrew, Aramaic and Greek Scriptures into the 21st-century Czech language.

Avoiding literalism on the one hand and a free paraphrase on the other, it strives to communicate clearly, yet faithfully, both the meaning and the literary style of the biblical writings. A team of evangelical translators and linguists, led by Alexandr Flek, dedicated 15 years to this translation. Since 2009, when it was first published, Bible21 has become widely popular among Czech churches and the general public.
