The field of blood

Matthew 27:8 Wherefore that field was called, The field of blood, unto this day.

Acts 1:19 And it was known unto all the dwellers at Jerusalem; insomuch as that field is called in their proper tongue, Aceldama, that is to say, The field of blood.

Is this a contradiction or is there a bigger story here.

Nehemiah 7:61 And these [were] they which went up [also] from Telmelah, Telharesha, Cherub, Addon, and Immer: but they could not shew their father’s house, nor their seed, whether they [were] of Israel.

Genesis 25:25 And the first came out red, all over like an hairy garment; and they called his name Esau.

Genesis 25:30 And Esau said to Jacob, Feed me, I pray thee, with that same red [pottage]; for I [am] faint: therefore was his name called Edom.
