The main text font for this site is Gentium Plus (which does not include glyphs for Hebrew). If you have Linux Libertine, or Brill, or Charis SIL on your system, those fonts are also in our font stack.
What you see: šḇilāʾ, ʾurḥāʾ

It is recommended that the SBL Hebrew font is installed for best results. The Culmus Project produces excellent Hebrew unicode fonts, and Taamey Frank (scroll down to fourth font) is in our font stack, as is Ezra SIL.
What you see: שִׁבֹּלֶת‎, ישֵׁב הַכְּרוּבִים

Gentium Plus (see above) includes a full and attractive set of Greek characters. We also make use of SBL Greek, and Palatino Linotype which is pre-installed on many Windows systems.
What you see: σχοῖνος, ὁ καθήμενος ἐπὶ τῶν χερουβιν

SAHD articles make limited use of Syriac; currently the display font is set to Estrangelo Edessa, part of the Meltho Syriac Fonts project.
