Word: thirty in Deuteronomy

And the space in which we came from Kadeshbarnea, until we were come over the brook Zered, was thirty and eight years; until all the generation of the men of war were wasted out from among the host, as the LORD sware unto them.

Deuteronomy 34:8

And the children of Israel wept for Moses in the plains of Moab thirty days: so the days of weeping and mourning for Moses were ended.
