'What is Good' in the Bible

And Elkanah her husband said to her - Do what is good in thine own eyes, tarry until thou have weaned him, only may Yahweh establish his word! So the woman tarried, and nursed her son, until she weaned him.

So Samuel told him all the words, and hid nothing from him. And he said, Yahweh, he is; what is good in his own eyes, let him do.

Then said he unto all Israel - Ye, shall be on one side, and, I and Jonathan my son, will be on the other side. And the people said unto Saul, What is good in thine eyes, do!
