Persevere the words of God and make right decision

Jeremiah 40:1-16
The commander of the guard found Jeremiah was being carried into exile to Babylon, he said to him,"The Lord your God decreed this disaster for this place. And now the Lord has brought it about; he has done just as he said he would. All this happened because your people sinned against the Lord and did not obey him."
The commander gave Jeremiah provisions and a present and let him go wherever he please. Jeremiah went to Gedaliah and stayed with him among the people who were left behind in the land.
Gedalish to be appointed king as governor over the and and had put him in charge of the men, women and children who were the poorest in the land and who had not been carried into exile to Babylon. People gathered from field to Gedalish. Gedalish ignored warning about Ishmael comes to take his life.
Why?
The words of the Lord has been done as he said, Jeremiah was set to free, Gedalish will be assassinated and all people in Jerusalem and Judah will scatter and be ruined for 70 years.
Even the commander of Babylonian knows that people in Judah sinned against the Lord, and did not obey the Lord.
Gedaliah makes a good start as governor. With Jerusalem in ruins he makes his headquarters at Mipah, 8km/5 miles to the north-west. Those who had fled before the army, escaping to neighboring countries, return and they gather in a good harvest, after the hungry days of occupation.
How?
Do not be a stick-necked man, don't ignore the warning from others. O, Lord give me the wisdom to persevere the words of God and make right decision, to be a gentleman.
