The Hebrew root aman means firm, something that is supported or secure. This word is used in Isaiah 22:23 for a nail that is fastened to a "secure" place. Derived from this root is the word emun meaning a craftsman. A craftsman is one who is firm and secure in his talent. Also derived from aman is the word emunah meaning firmness, something or someone that is firm in their actions. When the Hebrew word emunah is translated as faith misconceptions of its meaning occur. Faith is usually perceived as a knowing while the Hebrew emunah is a firm action. To have faith in God is not knowing that God exists or knowing that he will act, rather it is that the one with emunah will act with firmness toward God's will.
