[BASIC] [LED] Making two LEDs light at once

Other Hardware LEDs and Multiplexing
1

I'm trying to make two LEDs light up at once, on two different pins.

This is what I have written for my 6 LED sequence testing.

const int pin1 = 3;
const int pin2 = 4;
const int pin3 = 5;
const int pin4 = 6;
const int pin5 = 7;
const int pin6 = 8;

void setup()
{
pinMode(pin1, OUTPUT);
pinMode(pin2, OUTPUT);
pinMode(pin3, OUTPUT);
pinMode(pin4, OUTPUT);
pinMode(pin5, OUTPUT);
pinMode(pin6, OUTPUT);
}

void loop()
{
  digitalWrite(pin1, HIGH);
  delay(100);
  digitalWrite(pin1, LOW);
  digitalWrite(pin4, HIGH);
  delay(100);
  digitalWrite(pin4, LOW);
  digitalWrite(pin2, HIGH);
  delay(100);
  digitalWrite(pin2, LOW);
  digitalWrite(pin5, HIGH);
  delay(100);
  digitalWrite(pin5, LOW);
  digitalWrite(pin3, HIGH);
  delay(100);
  digitalWrite(pin3, LOW);
  digitalWrite(pin6, HIGH);
  delay(100);
  digitalWrite(pin6, LOW);
  delay(2000);
  
  
  digitalWrite(pin1, HIGH);
  delay(100);
  digitalWrite(pin1, LOW);
  digitalWrite(pin2, HIGH);
  delay(100);
  digitalWrite(pin2, LOW);
  digitalWrite(pin3, HIGH);
  delay(100);
  digitalWrite(pin3, LOW);
  digitalWrite(pin6, HIGH);
  delay(100);
  digitalWrite(pin6, LOW);
  digitalWrite(pin5,HIGH);
  delay(100);
  digitalWrite(pin5, LOW);
  digitalWrite(pin4, HIGH);
  delay(100);
  digitalWrite(pin4, LOW);
  delay(500);
  
  digitalWrite(pin4, HIGH);
  delay(100);
  digitalWrite(pin4, LOW);
  digitalWrite(pin5, HIGH);
  delay(100);
  digitalWrite(pin5, LOW);
  digitalWrite(pin6, HIGH);
  delay(100);
  digitalWrite(pin6, LOW);
  digitalWrite(pin3, HIGH);
  delay(100);
  digitalWrite(pin3, LOW);
  digitalWrite(pin2, HIGH);
  delay(100);
  digitalWrite(pin2, LOW);
  digitalWrite(pin1, HIGH);
  delay(100);
  digitalWrite(pin1, LOW);
  delay(2000);  
}

I want to pin1 and pin4 light up at the same time. I can't figure out how to make it happen.

I want to pin1 and pin4 light up at the same time

digitalWrite(pin1, HIGH);
digitalWrite(pin4, HIGH);
delay(100);
digitalWrite(pin1, LOW);
digitalWrite(pin4, LOW);

Of course it would be that simple.... It was looking me straight in the face. Thank you very much!
