Our child was due April 15. With that in mind, here is Psalm 15, instead of a hymn.

Psalm 15 (link takes you to NIV text)
1 Lord, who shall abide in thy tabernacle? who shall dwell in thy holy hill?
2 He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart.
3 He that backbiteth not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour.
4 In whose eyes a vile person is contemned; but he honoureth them that fear the LORD. He that sweareth to his own hurt, and changeth not.
5 He that putteth not out his money to usury, nor taketh reward against the innocent. He that doeth these things shall never be moved.
