Iyar is the second of the twelve months of the Jewish calendar. In the Bible, the month of Iyar is often called the month of Ziv, meaning "radiance." This month is commonly referred to as the month of (natural) healing. It's name is an acronym for "I AM God your Healer." (Exodus 15:26)
Iyar is associated with the tribe of Issachar, which is known for it's anointing to understand the times and to understand secrets.
This month is linked with light, which signifies increased revelation. Light is the opposite of darkness. If darkness tries to overtake you, this month say "No. I am increasing in revelation." Isaiah 60 says that the glory can be seen on you and radiates off of you. This is the month you need to light up with His glory.
To understand Iyar, we can look at what happened to Israel coming out of Egypt..
