Ezekiel 5:2

2. Burn… when the days of the siege are fulfilled This would indicate that, although so closely following the command to lie upon his side (Ezekiel 4:4, etc.), the acting out of this symbolic picture must be delayed until his one hundred and ninety days of silent and motionless watching of the besieged city are finished. The hair will then be burned on the tile in the midst of the besieged city (Ezekiel 4:1).

Smite about it with a knife “It” refers to the city, as is seen from Ezekiel 5:12. The prophet must throw the second lot of hair “about the city” and smite it as it falls. The meaning is that those who escape from the famine and pestilence within the city will fall by the sword outside the gates.

I will draw out a sword Those who do not fall in the city or its suburbs, but fly to distant places, will not escape. Jehovah’s sword in the hand of the heathen will still follow them (Jeremiah 9:16).
