The time when people have different languages
People on earth that time has only one language making themselves understand to each other. There is a time when people agreed to each other and they plan to build a tower which will reach into heaven and making themselves known to other people on earth. God did notice about the building of the tower and he was not happy with it , he did make all the people building the tower speaking into different languages. People are confused with each other and the building of the tower has stopped after the event. The Tower was called "Tower of Babel" after.
People are scattered in every parts of the earth with different languages. Many years past at the lineage of Shem , one of Noah's son. Abra was born , and he got married with Sarai which they are childless that time.
We should listen to God's command always and never to do unpleasant things which makes him disappoint.
