Genesis 19:19 http://www.blueletterbible.org/Bible.cfm?b=Gen&c=19&v=19&t=KJV#19
Psalm 136 has 'mercy' in it 26 times and it has 26 verses. This is in the Authorised Version of the Bible. Strangely, the New International Version of the Bible does not have this word, 'mercy', in it at all, but has 'love' substituted for 'mercy'. And according to my dictionary, 'love' is different to 'mercy'.
The word "mercy" is in the King James Version of the Bible 276 times. It is in 261 verses.
The word "mercy" appears 262 times in the KJV.

It will depend on what version of the bible you use. Some use mercy and others use lovingkindness. They mean basically the same. Mercy is used in different ways so you will have to go to the context to understand what the word means. This is not new to the bible. This is what happens in any language.

The donkey. The word "ass" meaning donkey is in the King James version of the Bible, published in 1611.
That word is not in the Bible.
The bible has been edited and modified to better fit current word usage, but the number of times the word thy (or the) is used in the bible (according to the King James Edition) is 11245.
No. Mercy Me wrote it and recorded it first.
