'Late' in the Bible

Now the Philistine came forward early and late, and he took his stand [for] forty days.

It happened {late one afternoon} [that] David got up from his bed and walked about on the roof of the king's house, and he saw a woman bathing on her roof. Now the woman {was very beautiful}.

[It is] in vain for you who rise early [and] sit late, eating the bread of anxious toil, [when] thus he provides for his beloved in [his] sleep.
