Powershell Foreach Line In Text File

powershell foreach line in text file and i have one hosts file which is having multiple host names and IP addresses. Below is the example of the input file. I want to read each line and ping for the first host (Host1), then the second host (Host2) and then the third host (Host3).

While pinging each host name, I need to check the ping response IP address for that host and match it back with the IP address mentioned in the input file. Below is the snippet of code with which am trying to read the file in the above format, but it is not working in that way. Host1 Host2 Host3 Host4 Host5 Host6

 $lines = Get-Content myfile.txt
    $lines |
         Test-Connection  $_.Split(' ')[1]


$lines = Get-Content myfile.txt | Where {$_ -notmatch '^\s+$'}
foreach ($line in $lines) {
    $fields = $line -split '\s+'
    $ip = $fields[0]
    $hosts = $fields[1..3]
    foreach ($h in $hosts) {
        $hostIP = (Test-Connection $h -Count 1).IPV4Address.ToString()
        if ($hostIP -ne $ip) { "Invalid host IP $hostIP for host $h" }

foreach ($line in $lines.Split('\r\n')){
    Test-Connection  $line.Split(' ')[1]
