'Kept' in the Bible

because Abraham obeyed my voice, and kept my requirements, my commandments, my statutes, and my laws."

While he was yet speaking with them, Rachel came with her father's sheep, for she kept them.

His brothers envied him, but his father kept this saying in mind.

He isn't greater in this house than I, neither has he kept back anything from me but you, because you are his wife. How then can I do this great wickedness, and sin against God?"
