Easter not biblical
Resurrection of Jesus Christ (Yeshua Hamashiac in Hebrew) is connected to the feast of Passover that will be celebrated on April 22 this year.  Easter has nothing to do with Yeshua and His resurrection.
Easter is an english transliteration for Ishtar.  The name Ishtar is most recognizable in Assyrian regions.  You can find this name in the Bible, but there this goddess will be called Ashtoreth which is the Phoenician name.  Ishtar and her story goes all the way back to Nimrod’s times where people announced Nimrod the sun god.  Read the whole story here: https://worldsymbolsblog.wordpress.com/2015/04/03/the-origins-of-passover-and-easter/
Every time when YHVH talks about Ashtoreth, He is angry with those who worship her and her symbols, like eggs for example. Egg is a symbol of her fertility. Ishtar supposedly flew from the moon in her egg and was reborn from it.  
Thats what YHVH thinks about Ashtoreth and all the idols connected to the sun god religion:
"Because that they have forsaken me, and have worshipped Ashtoreth the goddess of the Zidonians, Chemosh the god of the Moabites, and Milcom the god of the children of Ammon, and have not walked in my ways, to do that which is right in mine eyes, and to keep my statutes and my judgments, as did David his father.” — 1 Kings 11:33
"3  Thou shalt have no other gods before me.
4  Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:
5  Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me; ” — Exodus 20:3-5
“Your eyes have seen what the Lord did because of Baal–peor: for all the men that followed Baal–peor, the Lord thy God hath destroyed them from among you.” — Deuteronomy 4:3
“They joined themselves also unto Baal–peor, and ate the sacrifices of the dead.” — Psalm 106:28
“11  And the children of Israel did evil in the sight of the Lord, and served Baalim:
12  And they forsook the Lord God of their fathers, which brought them out of the land of Egypt, and followed other gods, of the gods of the people that were round about them, and bowed themselves unto them, and provoked the Lord to anger.
13  And they forsook the Lord, and served Baal and Ashtaroth.
14  And the anger of the Lord was hot against Israel, and he delivered them into the hands of spoilers that spoiled them, and he sold them into the hands of their enemies round about, so that they could not any longer stand before their enemies.” — Judges 2:11-14
And many, many more...
