SSH keys
First of all, the best solution for you would be to create new ssh keypair and use this key to login to all your servers (or some, based on preferences). If you don't know how, you can find it many times here on stackexchange, but shortcut:

Code:
ssh-keygen; ssh-copy-id your-host

Basically you should set passphrase for your key, so you will log in only once with the one password.

SSH pass
But if you really insist on using your passwords from files, you can do it quite simply as described in comments:

Code:
sshpass -f /path/to/myfile ssh user@localhost

But note that this is not really preferred method of using ssh with passwords stored in plaintext.

Expect
You can do the same thing using expect script like this:

Code:
#!/usr/local/bin/expect
spawn  ssh user@yourserver.com
expect "password:"
send "your_password\n";
interact

gnome-ssh-askpass

GNOME-SSH-ASKPASS(1)					      General Commands Manual					      GNOME-SSH-ASKPASS(1)

NAME

       gnome-ssh-askpass - prompts a user for a passphrase using GNOME

SYNOPSIS

       gnome-ssh-askpass

DESCRIPTION

       gnome-ssh-askpass  is  a GNOME-based passphrase dialog for use with OpenSSH.  It is intended to be called by the ssh-add(1) program and not
       invoked directly.  It allows ssh-add(1) to obtain a passphrase from a user, even if not connected to a terminal (assuming that an X display
       is  available).	This happens automatically in the case where ssh-add is invoked from one's ~/.xsession or as one of the GNOME startup pro-
       grams, for example.

       In order to be called automatically by ssh-add, gnome-ssh-askpass should be installed as /usr/bin/ssh-askpass.

ENVIRONMENT VARIABLES

       The following environment variables are recognized:

       GNOME_SSH_ASKPASS_GRAB_SERVER
	      Causes gnome-ssh-askpass to grab the X server before asking for a passphrase.

       GNOME_SSH_ASKPASS_GRAB_POINTER
	      Causes gnome-ssh-askpass to grab the mouse pointer using gdk_pointer_grab() before asking for a passphrase.

       Regardless of whether either of these environment variables is set, gnome-ssh-askpass will grab the keyboard using gdk_keyboard_grab().

AUTHOR

       This manual page was written by Colin Watson <cjwatson@debian.org> for the Debian system (but may be used by others).  It was based on that
       for x11-ssh-askpass by Philip Hands.
