We perform an analysis of the QCD lattice data on the baryon octet anddecuplet masses based on the relativistic chiral Lagrangian. The baryon selfenergies are computed in a finite volume at next-to-next-to-next-to leadingorder (N$^3$LO), where the dependence on the physical meson and baryon massesis kept. The number of free parameters is reduced significantly down to 12 byrelying on large-$N_c$ sum rules. Altogether we describe accurately more than220 data points from six different lattice groups, BMW, PACS-CS, HSC, LHPC,QCDSF-UKQCD and NPLQCD. Values for all counter terms relevant at N$^3$LO arepredicted. In particular we extract a pion-nucleon sigma term of 39$_{-1}^{+2}$MeV and a strangeness sigma term of the nucleon of $\sigma_{sN} = 84^{+28}_{-\;4}$ MeV. The flavour SU(3) chiral limit of the baryon octet anddecuplet masses is determined with $(802 \pm 4)$ MeV and $(1103 \pm 6)$ MeV.Detailed predictions for the baryon masses as currently evaluated by the ETMlattice QCD group are made.
