'Kept' in the Bible

In the evening she went, and on the next day she returned into the second women's house, to the custody of Shaashgaz, the king's eunuch, who kept the concubines. She came in to the king no more, unless the king delighted in her, and she was called by name.

and that these days should be remembered and kept throughout every generation, every family, every province, and every city; and that these days of Purim should not fail from among the Jews, nor the memory of them perish from their seed.
