'Well pleasing' in the Bible

And Aaron spake unto Moses, Behold, this day have they offered their sin-offering and their burnt-offering before Jehovah; and there have befallen me such things as these: and if I had eaten the sin-offering to-day, would it have been well-pleasing in the sight of Jehovah?

And when Moses heard that , it was well-pleasing in his sight.

Have I given orders for such a day as this? a day for keeping yourselves from pleasure? is it only a question of the bent head, of putting on haircloth, and being seated in the dust? is this what seems to you a holy day, well-pleasing to the Lord?
